Abstract:
Ten newborn kids were used to evaluate the relationship between apoptosis and passive immune transfer in neonatal enterocytes. Kids were slaughtered in groups of 2 at birth, 1, 2, 3, or 60 d postpartum, and samples of duodenal epithelium collected from each animal. Samples were fixed, dehydrated, and embedded in paraffin wax. Sections were assessed for apoptotic cells and immunostained for IgG. Our results suggest that IgG absorption is mediated by apoptotic enterocytes. Thus, delaying apoptosis may improve the success of passive immune transfer.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
