RESUMEN

OBJECTIVE: This study examined the prevalence, severity and risk factors of anaemia among adult people living with HIV attending an antiretroviral therapy centre in Woreta Primary Hospital, Woreta town, Ethiopia. DESIGN: Hospital-based retrospective cross-sectional study. SETTING: Public health facility that provides HIV care in Woreta town. PARTICIPANTS: A total of 289 medical records of adults living with HIV/AIDS on highly active antiretroviral therapy from February 2019 to September 2023 at government hospital were reviewed using a systematic sampling method. The data were entered using Epi-info V.7 and exported to SPSS V.23 for data analysis. The data were analysed using bivariate and then multivariate logistic regression models in order to identify variables associated with anaemia. At the 95% CI level, variables having a p value of <0.05 were deemed to be statistically significant predictors. PRIMARY OUTCOME: Prevalence and severity of anaemia and its predictors among adult patients living with HIV on antiretroviral therapy in Woreta Primary Hospital. RESULTS: The total prevalence of anaemia was 31.5% (95% CI 28.9 to 33.8). The prevalence of mild, moderate and severe anaemia was 20.42%, 10.38% and 0.70%, respectively. Predictors independently linked with anaemia were female sex (adjusted OR (AOR) 1.08), age ≥40 years (AOR 1.21), lived with HIV >10 years (AOR 2.31), CD4 counts <200 cells/µL (AOR 3.81), non-suppressed viral load (AOR 1.28), history of opportunistic infections (AOR 1.54), WHO clinical stages III and IV (AOR 1.37 and 2.23, respectively) and history of parasitic infestation (AOR 2.81). CONCLUSIONS: A sizeable proportion of participants were found anaemic. Female sex, older age, longer periods lived with the virus, lower CD4 count, non-suppressed viral load, history of opportunistic infections, WHO clinical stages III and IV and history of parasitic infestation were the contributing factors. Therefore, to improve the anaemic status and living circumstances of patients living with HIV, immediate action on the linked factors is needed, such as monitoring for maintenance of CD4 counts >200 cells/µL and avoiding progression of HIV to the advanced WHO clinical stages, suppressed viral load, preventing opportunistic infections and parasitic infestation.

RESUMEN

BACKGROUND: An increase in the prevalence of HIV drug resistance (HIVDR) has been reported in recent years, especially in persons on non-nucleoside reverse transcriptase inhibitors (NNRTIs) due to their low genetic barrier to mutations. However, there is a paucity of epidemiological data quantifying HIVDR in the era of new drugs like dolutegravir (DTG) in sub-Saharan Africa. We, therefore, sought to determine the prevalence and correlates of viral load (VL) suppression in adult people with HIV (PWH) on a fixed-dose combination of tenofovir disoproxil fumarate/lamivudine/dolutegravir (TLD) or tenofovir alafenamide/emtricitabine/dolutegravir (TAFED) and describe patterns of mutations in individuals failing treatment. METHODS: We conducted a cross-sectional study among 384 adults living with HIV aged ≥15 years between 5th June 2023 and 10th August 2023. Demographic, laboratory and clinical data were collected from electronic health records using a data collection form. Viral load suppression was defined as plasma HIV-1 RNA VL of <1000 copies/ml after being on ART for ≥ 6 months. SPSS version 22 to analyze the data. Descriptive statistics and logistic regression were the statistical methods used. RESULTS: The median (interquartile range (IQR)) age was 22 (IQR 18, 38) years, and 66.1% (n = 254) were females. VL suppression was 90.4% (n = 347); (95% confidence interval (CI) 87.6%-93.6%) after switching to TLD/TAFED. Among the virally suppressed, the majority (67.1%, n = 233) were female. Those who missed ≥2 doses in the last 30 days prior to the most recent review were less likely to attain viral suppression compared to those who did not miss any dose (adjusted odds ratio (AOR) 0.047; 95% CI 0.016-0.136; p<0.001). Four participants had resistance mutations to lamivudine and tenofovir. The most common NRTI mutations were M184MV and K65R while K101E was the most common NNRTI mutation. CONCLUSION: Our findings show that viral suppression was high after switching to TLD/TAFED; but lower than the last 95% target of the UNAIDS. Adherence to antiretroviral therapy was a significant correlate of VL suppression. We, therefore, recommend prompt switching of PWH to TLD/TAFED regimen and close monitoring to enhance adherence to therapy.

RESUMEN

BACKGROUND: Head-to-head data for bictegravir/emtricitabine/tenofovir alafenamide (BIC/F/TAF; B) and darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/c/F/TAF; D) are lacking in the context of rapid antiretroviral therapy (ART) initiation. This study, BIC-T&T, evaluates the efficacy and tolerability of B vs D in a UK test-and-treat setting. SETTING: BIC-T&T was a randomised, open-label, multi-centre, study in which participants initiated ART within 14 days after confirmed HIV-1 diagnosis before baseline laboratory. METHODS: The primary endpoint is the virological response (HIV RNA < 50copies/mL) at week 12 by time-weighted average change in log10 HIV RNA recorded in viral load assays from treatment initiation to week 12, using two-sample Wilcoxon rank-sum test. RESULTS: 36 participants were randomised: 94% were male, 53% white; mean (SD) age was 35 years (11.8). Baseline mean (±SD) log10 HIV-RNA was 4.79 (± 0.87) log10 copies/mL and CD4 505 (±253) cells/mm3. The mean (±SD) time from confirmed HIV diagnosis to ART initiation was 7.9 (± 3.7) days. The time-weighted mean decrease in log10 HIV RNA from treatment initiation to week 12 was significantly greater in B in comparison to D (3.1 vs. 2.6 log10 copies/mL, p < 0.001). Both regimens demonstrated good tolerability with infrequent laboratory abnormalities and no grade 3 or 4 adverse events. CONCLUSION: In this first head-to-head study in the context of ART initiation, HIV RNA decline from baseline to week 12 was significantly more rapid for BIC/F/TAF compared with DRV/c/F/TAF.

RESUMEN

Mitochondria-targeting agents, known as mitocans, are emerging as potent cancer therapeutics due to pronounced metabolic and apoptotic adaptations in the mitochondria of cancer cells. ONC212, an imipridone-family compound initially identified as a ClpP agonist, is currently under investigation as a potential mitocan with demonstrated preclinical efficacy against multiple malignancies. Despite this efficacy, the molecular mechanism underlying the cell death induced by ONC212 remains unclear. This study systematically investigates the mitochondrial involvement and signaling cascades associated with ONC212-induced cell death, utilizing HeLa and A549 cancer cells. Treated cancer cells exhibited characteristic apoptotic features, such as annexin-V positivity and caspase-3 activation; however, these occurred independently of typical mitochondrial events like membrane potential loss (ΔΨm) and cytochrome c release, as well as caspase-8 activation associated with the extrinsic pathway. Additionally, ONC212 treatment increased the expression of anti-apoptotic proteins Bcl-2 and Bcl-xL, which impeded apoptosis, as the overexpression of Bcl-2-GFP and Bcl-xL-GFP significantly reduced ONC212-mediated cell death. Furthermore, combining a sub-lethal dose of the Bcl-2/Bcl-xL inhibitor Navitoclax with ONC212 markedly augmented caspase-3 activation and cell death, still without any notable ΔΨm loss or cytochrome c release. Moreover, inhibition of caspase-9 activity unexpectedly augmented, rather than attenuated, caspase-3 activation and the subsequent cell death. Collectively, our research identifies ONC212 as an atypical mitochondrial-independent, yet Bcl-2/Bcl-xL-inhibitable, caspase-3-mediated apoptotic cell death inducer, highlighting its potential for combination therapies in tumors with defective mitochondrial apoptotic signaling.

RESUMEN

BACKGROUND: Patients with psoriatic arthritis (PsA) often suffer from anxiety disorders. While upadacitinib has shown effectiveness in reducing various disease activity indicators in active PsA, its impact on anxiety disorders in PsA patients needs further investigation. METHODS: In this 12-week randomized, open-label, controlled trial, PsA patients with coexisting anxiety were randomly assigned to either the upadacitinib group or the adalimumab group in a 1:1 ratio. The upadacitinib group received a daily dose of 15 mg, while the adalimumab group received 40 mg every 2 weeks. The primary outcome measured the change in Hospital Anxiety Self-Assessment Scale (HADS-A) total scores after the 12-week intervention. Secondary outcomes included changes in the Health Assessment Questionnaire-Disability Index (HAQ-DI), the percentage of participants meeting the ACR20 criteria compared to baseline after 12 weeks, and the percentage of participants achieving a grade 0 or 1 in the psoriasis static Investigator's overall assessment (sPGA) at week 12 with an improvement of at least 2 points from baseline (sPGA 0/1). One-way analysis of variance (ANOVA) was used to compare the means of normally distributed variables between the upadacitinib and adalimumab groups. DISCUSSION: The impact of upadacitinib on anxiety in PsA patients remains uncertain. This 12-week open randomized controlled trial aims to provide insights into disease progression and underscore the importance of addressing PsA-related anxiety during treatment.

RESUMEN

BACKGROUND: A dolutegravir (DTG)-based antiretroviral regimen has been rolled out for pregnant women in low- and middle-income countries since 2020. However, available safety data are limited to a few clinical trials and observational studies. Hence, we present real-world pregnancy and birth outcome safety data from a large sample multicenter cohort study in Ethiopia. METHODS: A retrospective cohort study was conducted in fourteen hospitals across Ethiopia from 2017 to 2022. HIV-infected pregnant women were followed from the date of prevention of mother-to-child transmission (PMTCT) care enrolment until the infant was 6-8 weeks old. The primary safety outcome was a composite of adverse pregnancy events comprising spontaneous abortion, intrauterine fetal death (IUFD) before onset of labor, preterm birth, and maternal death. Additionally, a composite adverse birth outcome was assessed, comprising intrapartum fetal demise, low birth weight, and neonatal death. Finally, a composite of adverse pregnancy or birth outcome was also investigated. The exposure of interest was the antiretroviral treatment (ART) regimen used during pregnancy for PMTCT of HIV. RESULTS: During the study period, 2643 women were enrolled in routine PMTCT care. However, 2490 (92.2%) participants were eligible for the study. A total of 136/1724 (7.9%, 95% CI: 6.7-9.3%) women experienced adverse pregnancy outcomes. Fewer women in the DTG-based group (5.4%, 95% CI: 3.7-7.5%) had adverse pregnancy outcomes than in the Efavirenz (EFV)-based group (8.3%, 95% CI: 6.6-10.3%), P = 0.004. After controlling for baseline differences, the DTG group had a 43% lower risk of adverse pregnancy outcomes (adjusted odd ratio (AOR), 0.57; 95% CI, 0.32-0.96%) and a 53% lower risk of preterm birth (AOR, 0.47; 95% CI, 0.22-0.98%) compared to the EFV group. A total of 103/1616 (6.4%, 95% CI: 5.2-7.7%) women had adverse birth outcomes. Although the difference was not statistically significant, fewer women in the DTG group (30/548; 5.5%, 95% CI: 3.7-7.7%) than in the EFV group (57/830; 6.9%, 95% CI: 5.2-8.8%) had adverse birth outcomes. CONCLUSIONS: In this study, we observed that DTG-based regimens were associated with better pregnancy and birth outcome safety profiles, reaffirming the WHO recommendation. However, a prospective study is recommended to assess uncaptured maternal and perinatal adverse outcomes, such as congenital abnormalities, and infant growth and neurocognitive development.

RESUMEN

The paper reports new multifunctional plant biostimulant formulations obtained via in situ hydrogelation of chitosan with salicylaldehyde in the presence of a mimetic naphthalimide-based strigolactone, in specific conditions. Various analytical techniques (FTIR, 1H NMR, SEM, POM, TGA, WRXD) were employed to understand the particularities of the hydrogelation mechanism and its consequences on the formulations' properties. Further, in order to evaluate their potential for the targeted application, the swelling in media of pH characteristic for different soils, water holding capacity, soil biodegradability, in vitro release of the strigolactone mimic and impact on tomatoes plant growth in laboratory conditions were investigated and discussed. It was found that the strigolactone mimic has the ability to bond to the chitosan matrix via physical forces, favoring a prolonged release. Moreover, the combination of chitosan with the strigolactone mimic in an optimal mass ratio triggered a synergistic effect on the plant growth, up to 4 times higher compared to the neat control soil.

RESUMEN

This study reports a new series of 1,10-phenanthroline-substituted imidazolium salts (1a-f), examining their design, synthesis, structure and anticancer activities. The structures of these salts (1a-f) were characterized using 1H, 13C NMR, elemental analysis, mass spectrometry and Fourier transform infrared (FT-IR) spectroscopies. The salts' cytotoxic activities were tested against cancer cell lines, specifically MCF-7, MDA-MB-231 and non-tumorigenic MCF-10A mammary cells. The study compared the impact of aliphatic and benzylic groups in the salts' structure on their anticancer activity. Screening results revealed that compound 1c, in particular, showed promising inhibitory activity against the growth of MDA-MB-231 breast cancer cells, with an IC50 value of 12.8 ± 1.2 µM, indicating its potential as a chemotherapeutic agent. Cell apoptosis analysis demonstrated a tendency for compound 1c to induce early apoptosis in breast cancer cells. The stability/aquation of compound 1c was investigated using 1H NMR spectroscopy and its binding modes with DNA were explored via UV-Vis spectroscopy. Additionally, the study investigated the interaction residues and docking scores of compound 1c and the reference drug doxorubicin against Bax and Bcl-2 proteins using molecular docking.

RESUMEN

Purpose: Amyopathic dermatomyositis (ADM) is a rare, idiopathic, connective tissue disease and melanoma differentiation-associated protein 5 (MDA5) antibody-positive ADM is more treatment-resistant, especially in patients with interstitial lung disease (ILD). The purpose of this article is to report a case of anti-MDA5-positive ADM successfully treated with JAK inhibitor Upadacitinib.Materials and methods: A 35-year-old Chinese woman presented with recurrent itchy erythema on her face and scalp for 4 years. Upon examination, there were heliotrope erythema and eyelid edema, reddish rash on neck and scalp. Biopsy of the lesions was consistent with DM and a line blot assay confirmed the presence of anti-MDA5 antibodies. This patient was treated with oral Upadacitinib at a dosage of 30 mg daily.Results: After 6 weeks of treatment, she achieved complete clinical remission with no reported side effects or instances of relapse. The antibody titer of anti-MDA5 was also decreased.Conclusions: Upadacitinib may be a potential drug candidate in patients with treatment-resistant ADM, especially in cases with refractory cutaneous conditions.

RESUMEN

INTRODUCTION: This study compared the clinical effectiveness of switching from tumor necrosis factor inhibitor (TNFi) to upadacitinib (TNFi-UPA), another TNFi (TNFi-TNFi), or an advanced therapy with another mechanism of action (TNFi-other MOA) in patients with rheumatoid arthritis (RA). METHODS: Data were drawn from the Adelphi RA Disease Specific Programme™, a cross-sectional survey administered to rheumatologists and their consulting patients in Germany, France, Italy, Spain, the UK, Japan, Canada, and the USA from May 2021 to January 2022. Patients who switched treatment from an initial TNFi were stratified by subsequent therapy of interest: TNFi-UPA, TNFi-TNFi, or TNFi-other MOA. Physician-reported clinical outcomes including disease activity (with formal DAS28 scoring available for 29% of patients) categorized as remission, low/moderate/high disease activity, as well as pain were recorded at initiation of current treatment and ≥ 6 months from treatment switch. Fatigue and treatment adherence were measured ≥ 6 months from treatment switch. Inverse-probability-weighted regression adjustment compared outcomes by subsequent class of therapy: TNFi-UPA versus TNFi-TNFi, or TNFi-UPA versus TNFi-other MOA. RESULTS: Of 503 patients who switched from their first TNFi, 261 were in TNFi-UPA, 128 in TNFi-TNFi, and 114 in TNFi-other MOA groups. At the time of switch, most patients had moderate/high disease activity (TNFi-UPA: 73%; TNFi-TNFi: 52%; TNFi-other MOA: 60%). After adjustment for differences in characteristics at point of switch, patients in TNFi-UPA group (n = 261) were significantly more likely to achieve physician-reported remission (67.7% vs. 40.3%; p = 0.0015), no pain (55.7% vs. 25.4%; p = 0.0007), and complete adherence (60.0% vs. 34.2%; p = 0.0049) compared with patients in TNFi-TNFi group (n = 121). Similar findings were observed for TNFi-UPA versus TNFi-other MOA groups (n = 111). CONCLUSION: Patients who switched from TNFi to UPA had significantly better clinical outcomes of remission, no pain, and complete adherence than those who cycled TNFi or switched to another MOA.

RESUMEN

INTRODUCTION: Millions of people living with HIV (PLWH) take oral antiretroviral therapy (ART), which requires a lifetime of consistent medication adherence. The relationship between adherence and poor HIV outcomes is well documented. Newer ART regimens that include dolutegravir (DTG) could be more forgiving, but empirical evidence on the relationship between adherence and viral suppression under DTG is only emerging. METHODS: In this observational cohort study (secondary analysis of data from a randomized trial), we used data from 313 ART clients from a large HIV clinic in Kampala, Uganda. Over the 4-year study period (January 2018-January 2022), 91% switched from non-DTG regimens to DTG regimens. We measured adherence using Medication Event Monitoring Systems-caps and extracted prescription information and viral load measures from electronic health records. We estimated unadjusted linear regressions and adjusted models that included individual and time fixed-effects. RESULTS: Under non-DTG regimens, 96% of participants were virally suppressed (defined as viral load < 200 copies/ml) when adherence was 90% or higher in the 3 months before viral load measurement. Viral suppression was 32 percentage points lower when adherence was between 0% and 49% (95% CI -0.44, -0.20, p < 0.01), 12 percentage points lower when adherence was between 50% and 79% (95% CI -0.23, -0.02, p < 0.01), and not significantly different when adherence was between 80% and 89% (effect of 0.00, 95% CI -0.06, 0.07, p = 0.81). In contrast, for participants taking DTG, there was no statistically significant difference in viral suppression among any of the four adherence levels; more than 95% were virally suppressed at each adherence level. On average, switching to DTG increased viral suppression by 6 percentage points in our adjusted models (95% CI 0.00, 0.13, p = 0.03). CONCLUSIONS: There was no significant association between adherence levels and viral suppression among PLWH taking DTG regimens, suggesting a high degree of forgiveness for missed doses. The use of DTG should be prioritized over older regimens, particularly for those with low adherence. CLINICAL TRIAL NUMBER: NCT03494777.

RESUMEN

INTRODUCTION: Dolutegravir (DTG)-based antiretroviral therapy is the World Health Organization's preferred first-line regimen for all persons with HIV, including pregnant women. While DTG has been implicated as an obesogen associated with greater weight gain compared to other antiretrovirals, there is a paucity of data in pregnant women and their children. The Obesogenic oRigins of maternal and Child metabolic health Involving Dolutegravir (ORCHID) study is investigating associations between DTG, weight gain, and metabolic outcomes in the context of HIV. MATERIALS & METHODS: ORCHID is a prospective observational study taking place in Cape Town, South Africa (NCT04991402). A total of 1920 pregnant women with and without HIV infection are being followed from ≤18 weeks gestational age to 24 months postpartum with their children. Participants attend eleven study visits: 3 antenatal, delivery, and 7 postnatal visits. Several embedded sub-studies address specific scientific aims. Primary outcome measurements in mothers include anthropometry, blood pressure, body composition, dysglycemia, insulin resistance (IR), and dyslipidemia. Other maternal measures include demographics, resting energy expenditure, viral load, physical activity, dietary intake, hepatic steatosis, and repository specimens. Sub-study measurements include markers of adipose inflammation, gut integrity, and satiety/hunger, subcutaneous adipose tissue morphology and mitochondrial function, and metabolomics. Primary outcome measurements in children include anthropometry, adipose tissue mass, dysglycemia, IR, and dyslipidemia. Other variables include fetal growth, birth outcomes, medical/breastfeeding history, caloric intake, neurodevelopment, and repository specimens. Sub-study measurements include metabolites/lipid subspecies in umbilical cord blood, as well as breast milk composition and DTG exposure. DISCUSSION: ORCHID will play a pivotal role in defining obesogenic mechanisms and clinical consequences of DTG use in pregnancy in women with HIV and their children. It will provide insights into metabolic disease risk reduction in the context of HIV/DTG, identify intervention targets, and inform public health approaches to diminish chronic metabolic co-morbidities for women and children.

RESUMEN

Dolutegravir (DLG) has become a distinctive first-line antiretroviral therapy for the treatment of HIV in most countries due to its affordability, high efficacy, and low drug-drug interactions. However, the evaluation of genotoxic impurities (GTIs) in DLG and their toxicity assessment has not been explored thoroughly. Thus, in this study, a simple, fast, and selective analytical methodology was developed for the identification and determination of 7 GTIs in the comprehensive, explicit route of synthesis for the dolutegravir sodium (DLG-Na) drug. A facile, fast ultrasonication-assisted liquid-liquid extraction procedure was adapted to isolate the GTIs in DLG-Na and then analyzed using the gas chromatography (GC)-electron impact (EI)/mass spectrometer (MS) quantification (using selective ion monitoring mode) technique. This EI-GC/MS method was validated as per the current requirements of ICH Q2 (R1) guidelines. Under optimal method conditions, excellent linearities were achieved with R between 0.9959 and 0.9995, and high sensitivity was obtained in terms of detection limits (LOD) between 0.15 to 0.63 µg/g, and quantification limits (LOQ) between 0.45 to 1.66 µg/g for the seven GTIs in DLG. The obtained recoveries ranged from 98.2 to 104.3 % at LOQ, 15 µg/g, and 18 µg/g concentration levels (maximum daily dose of 100 mg). This developed and validated method is rapid, easy to adopt, specific, sensitive, and accurate in estimating the seven GTIs in a relatively complex sodium matrix of the DLG-Na drug moiety. As a method application, two different manufactured samples of DLG-Na drug substances were analyzed for the fate of the GTIs and drug safety for the intended dosage applications. Moreover, an in-silico QSAR toxicity prediction assessment was carried out to prove scientifically the potential GTI nature of each impurity from the alerting functional groups.

RESUMEN

PURPOSE OF REVIEW: To analyze the efficacy and safety of Janus kinase inhibitors (JAKi) in the treatment of pediatric AD. RECENT FINDINGS: Adolescents with moderate and severe atopic dermatitis (AD) need systemic therapies, as stated several recent practice guidelines. (JAKi) have shown their efficacy in the treatment of adult AD, however, there is a lack of information concerning efficacy and safety of their use in pediatric AD. We found that the JAKi's abrocitinib (ABRO), baricitinib (BARI), and upadacitinib (UPA), are all an effective treatment option with a very fast onset of action for adolescents with moderate-to-severe AD. BARI was not effective in children between 2 and 10 years with moderate-to-severe AD. Fortunately, major safety issues with JAKi in adolescents with AD have not been documented in the trials, so far, contrasting with the reports in adults with AD, where these events have very rarely occurred. There are some reports of herpes zoster (HZ) infection in adolescents on JAKi, but it is not a major safety concern. Acne is a relatively common AE with UPA in adolescents; however, it is responsive to standard treatment. This review will help the clinician to choose among the JAKi according to the needs and clinical features of patients with moderate and severe AD. In the following years, with the advent of new biologicals and JAKi, these therapies will fall into place in each phase of the evolution of patients with AD.

RESUMEN

Pseudomonas protegens can generally produce multiple antibiotics including pyoluteorin (Plt), 2,4-diacetylphloroglucinol (DAPG), and pyrrolnitrin (Prn). In this study, we discovered and characterized a quorum sensing (QS) system, PpqI/R, in P. protegens H78. PpqI/R, encoded by two open reading frames (ORFs) (H78_01960/01961) in P. protegens H78 genome, is a LuxI/R-type QS system. Four long-chain acyl homoserine lactone (AHL) signaling molecules, 3-OH-C10-HSL, 3-OH-C12-HSL, C12-HSL, and 3-OH-C14-HSL, are produced by H78. Biosynthesis of these AHLs is catalyzed by PpqI synthase and activated by the PpqR regulator in H78 and in Escherichia coli when heterologously expressed. PpqR activates ppqI expression by targeting the lux box upstream of the ppqI promoter in cooperation with corresponding AHLs. The four aforementioned AHLs exhibited different capabilities to induce ppqI promoter expression, with 3-OH-C12-HSL showing the highest induction activity. In H78 cells, ppqI/R expression is activated by the two-component system GacS/A and the RNA chaperone Hfq. Differential regulation of the PpqI/R system in secondary metabolism has a negative effect on DAPG biosynthesis and ped operon (involved in volatile organic compound biosynthesis) expression. In contrast, Plt biosynthesis and prn operon expression were positively regulated by PpqI/R. In summary, PpqI/R, the first characterized QS system in P. protegens, is activated by GacS/A and Hfq and controls the expression of secondary metabolites, including antibiotics.
