- Abstract
Little is known about lymphoid organ development in yaks. In this study, we characterize and evaluate the main markers of T cell, B cell, plasma cell and antigen-presenting cell in the mesenteric lymph nodes, spleen and hemal node in newborn, juvenile and adult yaks by immunohistochemistry, real-time quantitative polymerase chain reaction and western blotting. The structures of all organs were not fully developed in newborn. The CD3+ cells were mainly located in the paracortex area of the mesenteric lymph node and the T cell dependent area in the hemal node and spleen. CD79a+ cells were mainly detected in the lymphoid follicles. The expression of CD3 and CD79a increased from newborn to juvenile and then decreased in adults. The expression of CD3 was always higher in the spleen and CD79a was higher in the mesenteric lymph node. IgG+ and IgA+ cells were observed in all examined samples, except in newborn yak hemal node. IgG and IgA were up-regulated with age and the highest expression was observed in the mesenteric lymph node. The SIRPα and CD68 were widely expressed. A significant feature was that the SIRPα expression in the spleen was lowest in newborns but highest in juvenile and adult yaks. The expression of CD68 in the hemal node was highest in all groups and increased from newborn to adult yaks. This study sheds light on the relationship between the morphology and function of these organs and provides useful references for normal yak lymphoid organ development.
