Physiological Characterization of the Transporter-Mediated Uptake of the Reversible Male Contraceptive H2-Gamendazole Across the Blood-Testis Barrier.

J Pharmacol Exp Ther 2022 Jul 2. Epub 2022 Jul 2.

Pharmacology & Toxicology, University of Arizona, United States

The blood-testis barrier (BTB) is formed by a tight network of Sertoli cells (SCs) to limit the movement of reproductive toxicants from the blood into the male genital tract. Transporters expressed at the basal membranes of SCs also influence the disposition of drugs across the BTB. The reversible, non-hormonal contraceptive, H2-gamendazole (H2-GMZ), is an indazole carboxylic acid analog that accumulates over 10 times more in the testes compared to other organs. Read More

Sertoli Cell-Germ Cell Interactions Within the Niche: Paracrine and Juxtacrine Molecular Communications.

Front Endocrinol (Lausanne) 2022 10;13:897062. Epub 2022 Jun 10.

Department of Endocrine Neoplasia and Hormonal Disorders, MD Anderson Cancer Center, Houston, TX, United States.

Male germ cell development depends on multiple biological events that combine epigenetic reprogramming, cell cycle regulation, and cell migration in a spatio-temporal manner. Sertoli cells are a crucial component of the spermatogonial stem cell niche and provide essential growth factors and chemokines to developing germ cells. This review focuses mainly on the activation of master regulators of the niche in Sertoli cells and their targets, as well as on novel molecular mechanisms underlying the regulation of growth and differentiation factors such as GDNF and retinoic acid by NOTCH signaling and other pathways.

Unraveling mitochondrial piRNAs in mouse embryonic gonadal cells.

Sci Rep 2022 Jun 24;12(1):10730. Epub 2022 Jun 24.

Department of Cellular and Molecular Biology, Centro de Investigaciones Biológicas Margarita Salas C.I.B. (CSIC), Ramiro de Maeztu 9, 28040, Madrid, Spain.

Although mitochondria are widely studied organelles, the recent interest in the role of mitochondrial small noncoding RNAs (sncRNAs), miRNAs, and more recently, piRNAs, is providing new functional perspectives in germ cell development and differentiation. piRNAs (PIWI-interacting RNAs) are single-stranded sncRNAs of mostly about 20-35 nucleotides, generated from the processing of pre-piRNAs. We leverage next-generation sequencing data obtained from mouse primordial germ cells and somatic cells purified from early-differentiating embryonic ovaries and testis from 11. Read More

The Penis, the Vagina and HIV Risk: Key Differences (Aside from the Obvious).

Viruses 2022 May 27;14(6). Epub 2022 May 27.

Department of Microbiology and Immunology, Schulich School of Medicine and Dentistry, Western University, London, ON N6A 5C1, Canada.

Globally, most Human Immunodeficiency Virus type 1 (HIV) transmission occurs through vaginal-penile sex (heterosexual transmission). The local immune environment at the site of HIV exposure is an important determinant of whether exposure during sex will lead to productive infection, and the vaginal and penile immune milieus are each critically shaped by the local microbiome. However, there are key differences in the microbial drivers of inflammation and immune quiescence at these tissue sites. Read More
