Neutrophils are major effectors of acute inflammation against infection and tissue damage, with ability to adapt their phenotype according the microenvironment. Although sex hormones regulate adaptive immune cells, which explains differences in immunity infection, little information is available about effects androgens on neutrophils. We therefore aimed examine neutrophil recruitment plasticity androgen-dependent -independent sites under androgen manipulation. By using a bacterial model...
Androgen signaling in prostate smooth muscle cells (pSMCs) is critical for the maintenance of homeostasis, alterations which are a central aspect development pathological conditions. Testosterone can act through classic androgen receptor (AR) cytoplasm, eliciting genomic signaling, or different types receptors located at plasma membrane nongenomic signaling. We aimed to find evidence testosterone-signaling mechanisms pSMCs and their participation cell proliferation, differentiation,...
Candida albicans is the prevalent etiological agent in acute vulvovaginal infection and most severe chronic condition known as recurrent candidiasis (VVC). A critical role of local innate immunity defense pathogenesis vaginal by proposed. The fungal recognition immune receptor an essential step for induction responses including cytokines antimicrobial peptides (AMPs) production host protection. Using TLR2-deficient mice, we characterized early response during VVC. Intravaginal challenge...
Prostatic smooth muscle cells (pSMCs) differentiation is a key factor for prostatic homeostasis, with androgens exerting multiple effects on these cells. Here, we demonstrated that the myodifferentiator complex Srf/Myocd up‐regulated by testosterone in dose‐dependent manner primary cultures of rat pSMCs, which was associated to increase Acta2 , Cnn1 and Lmod1 expressions. Blocking Srf or Myocd siRNAs inhibited effect testosterone. While LPS led dedifferentiated phenotype characterized...
Androgen deprivation therapy (ADT) is the longstanding treatment for advanced prostate cancer (PC) because androgen receptor (AR) key therapeutic vulnerability this disease. Bipolar (BAT) - rapid cycling of supraphysiologic (SPA) and low serum testosterone levels an alternative concept, but not all patients respond acquired resistance can occur. In issue JCI, Sena et al. developed a gene signature indicative high AR activity to predict patient response BAT, including decline in both...

Abstract Background: Men with incurable castration resistant prostate cancer (CRPC) are typically treated taxanes; however, drug resistance rapidly develops. Thus, overcoming taxane PC is a major clinical need. We previously identified seven gene network in aggressive CRPC, which includes the mitotic serine threonine kinase BUB1 , regulator of spindle assembly checkpoint (SAC). Alterations kinases (and SAC malfunction) associated advanced and development thereby represent potential...
<div>Abstract<p>Men with advanced prostate cancer are treated by androgen deprivation therapy but the disease recurs as incurable castration-resistant (CRPC), requiring new treatment options.
