Özet

Calcium-binding proteins (CaBPs) have an essential role in male reproduction by modulating calcium ion metabolism. Although the brain and testis are structurally and functionally different, they show a high degree of transcriptomic and proteomic similarities. The purpose of the present study was to explore some CaBPs (Iba-1, Calbindin, Calretinin and Parvalbumin) and neural cell markers (CNPase, NG2 and Drebrin) expression in rat testis and epididymis during postnatal periods by using immunohistochemistry. Iba-1, calbindin, calretinin, parvalbumin, CNPase, NG2 and drebrin were expressed in the epididymal epithelium in each postnatal period. Iba-1 and calbindin expression showed stage-dependent expression in spermatids. CaBPs and neural cell markers showed a positive reaction in Leydig cells in the postpubertal and mature periods. Sertoli cells, gonocytes, spermatogonium, and peritubular myoid cells showed heterogeneity in the expression of CaBPs and nerve markers throughout postnatal development. Interestingly, CNPase, NG2 and drebrin were positive in spermatocytes, spermatids, and sperm. Expression dynamics of calcium-binding proteins and nerve markers showed differences in germ cells and somatic cells during postnatal development. The expression of these proteins in the testis and epididymis supports that they may have important roles in reproductive physiology.
