It is known that sperm and seminal plasma (SP) affect uterine immunity. In cattle, artificial insemination enables breeding by depositing frozen and largely diluted sperm with a negligible amount of SP into the uterus. Thus, the present study focused

Recently, we reported that sperm induce cluster of differentiation 44 (CD44) expression and Toll-like receptor 2 (TLR2)-mediated inflammatory response in bovine uterus. In the present study, we hypothesized that the interaction between CD44 of bovine

Toll-like receptor 2 (TLR2) is a major membrane-bound receptor with ligand and species specificity that activates the host immune response. Heterodimerization of TLR2 with TLR1 (TLR2/1) or TLR6 (TLR2/6), triggered by ligand binding, is essential to i

Toll-like receptor 2 (TLR2) signaling pathway is involved in the sperm-triggered uterine inflammatory response at insemination, but its precise mechanism at molecular-level remains unknown. According to the ligand specificity, TLR2 forms a heterodime

The aim of the present study was to detect the changes occurring in serum testosterone profile in male buffaloes. Thirty blood samples from apparently healthy slaughtered male buffaloes were taken and divided into three age groups, 1.5–1.8, 2 –2.

This study was performed to evaluate the protective effect of Avenanthramides (AVA) against testicular degeneration induced by cisplatin (CP) in rats. Thirty six male rats were equally divided into four groups: Group I served as control group, group

Two prostanglandins (luprostiol, LUP, and dinoprost, DIN) and two ovulation-inducing agents (human Chorionic Gonadotropin, hCG, and deslorelin, DES) were evaluated for luteolysis and estrus induction, and for ovulation induction, respectively, in emb

Sperm are allogenic to the female genital tract; however, oviducts provide optimal conditions for survival and capacitation of these non-self cells until fertilization. Recently, we showed that oviduct-conditioned media and prostaglandin E2 (PGE2) su

Gentamicin (GM) is an aminoglycoside that has harmful effects on the male germ cells and sperm quality. N-3 polyunsaturated fatty acids (n-3 PUFA) are natural antioxidants that influence cell signaling and inflammation. Heme-oxygenase-1 (HO-1) and he

Previously, we reported that polymorphonuclear neutrophils (PMNs) are constantly existent in the bovine oviduct fluid during the pre-ovulatory stage under physiological conditions. Moreover, incubation of PMNs with bovine oviduct epithelial cells-con
