IL11 activates the placental inflammasome to drive preeclampsia.

Introduction: Preeclampsia is a life-threatening disorder of pregnancy unique to humans. Interleukin (IL)11 is elevated in serum from pregnancies that subsequently develop early-onset preeclampsia and pharmacological elevation of IL11 in pregnant mice causes the development of early-onset preeclampsia-like features (hypertension, proteinuria, and fetal growth restriction). However, the mechanism by which IL11 drives preeclampsia is unknown.

Differential permeability of the blood-testis barrier during reinitiation of spermatogenesis in adult male rats.

The blood-testis barrier (BTB) sequesters meiotic spermatocytes and differentiating spermatids away from the vascular environment. We aimed to assess whether meiosis and postmeiotic differentiation could occur when the BTB is permeable. Using a model of meiotic suppression and reinitiation, BTB function was assessed using permeability tracers of small, medium, and large (0.

Retinoic acid promotes Sertoli cell differentiation and antagonises activin-induced proliferation.

From puberty and throughout adult spermatogenesis, retinoid signalling is essential for germ cell differentiation and male fertility. The initiation of spermatogonial differentiation and germ cell meiosis occurs under the direction of local retinoid signalling in the testis, and corresponds with the final phase of somatic Sertoli cell differentiation at puberty. Here, we consider the cellular and molecular basis of retinoid actions upon Sertoli cell differentiation.

Lentiviral transduction of rat Sertoli cells as a means to modify gene expression.

Primary cell culture is an established and widely used technique to study Sertoli cell function in vitro. However, the relative difficulty of stably overexpressing or knocking down genes in Sertoli cell culture has limited progress in the field. In this technical report, we present a method to transduce 20 dpp rat Sertoli cell cultures with VSV-G pseudotyped lentiviral based vectors at a high rate (~80%), with stable reporter gene expression.
