Male Reproductive Tract Pathophysiology
Researcher Profile: Dr. Fernando Pierucci-Alves

Sperm cells are immunogenic and, despite this, spend several days in the mammalian male body to mature and acquire fertilizing capacity. This occurs while sperm transit through the lumen of the male excurrent system. This duct system is composed by the efferent ducts, epididymis and vas deferens and is lined by epithelial cells carrying out an array of secretory and absorptive mechanisms. In addition, antigen presenting cells (APCs) of the immune system are in close contact with male duct epithelia. While epithelial cell function is required for successful sperm maturation, maintenance of adequate duct structure and fertility, the roles of APCs in the male duct system is poorly understood. My research program is focused on mechanisms that are carried out by these epithelia and APCs and are, as we hypothesize, required for immunotolerance to sperm. Specifically, we are studying the roles of transforming growth factor beta (TGFβ) in these tissues. My laboratory has determined that TGFβ-signaling occurs in both male duct epithelia and APCs and that it is required for immunotolerance to sperm. Murine animal models are employed to understand how disruptions in TGFβ-signaling lead to infertility associated with antisperm antibodies and leukocytospermia.

Renal Pathophysiology
Researcher Profile: Dr. Fernando Pierucci-Alves - Part II

Transforming growth factor beta (TGFβ) signaling is known to induce renal fibrosis. Our work is generating evidence to support the novel concept that in vivo increases in TGFβ-signaling also leads to renal cystic disease. Importantly, human patients presenting Marfan syndrome have systemic increases in TGFβ-signaling and develop significantly more (and more rapidly) renal cysts than the general population.
