Spermatogenesis is the cellular process by which spermatogonia develop into mature
spermatids within seminiferous tubules, the functional unit of the mammalian testis, under …

Tight junctions (TJs) are intercellular protein complexes that preserve tissue homeostasis
and integrity through the control of paracellular permeability and cell polarity. Recent …

The blood–brain barrier (BBB) is a dynamic and complex interface between blood and the
central nervous system that strictly controls the exchanges between the blood and brain …

The structure and function of the barrier layers restricting the free diffusion of substances
between the central nervous system (brain and spinal cord) and the systemic circulation is of …

The tight junction is a multi-protein complex and is the apical most junctional complex in
certain epithelial and endothelial cells. A great deal of attention has been devoted to the …

Tight junctions are a component of the epithelial junctional complex, and they form the
paracellular diffusion barrier that enables epithelial cells to create cellular sheets that …

Cyclin D1 is a critical regulator of cell cycle progression and works at the G1 to S-phase
transition. Here, we report the isolation and characterization of the novel c-Myc-regulated …

Spermatogenesis and oogenesis basic helix-loop-helix (bHLH) transcription factor 2
(Sohlh2) functions as a bhlh transcription factor to regulate mouse germ cell differentiation …

In the testis, tight junctions (TJs) are found between adjacent Sertoli cells at the level of the
blood–testis barrier (BTB) where they coexist with basal ectoplasmic specializations and …

Tight junctions of epithelial and endothelial cells form selective barriers that regulate
paracellular transport of solutes, immune cells, and drugs. Tight junctions consist of proteins …
