Overview

Randomized trial investigates immune splenic changes due to seasonal variation in dromedary camels, indicating adaptations to desert life.

Key Points

  • This research examines how seasonal changes affect the structure and function of the spleen in dromedary camels.
  • Spleen samples collected from adult male dromedary camels during winter and summer.
  • Samples analyzed using histological, semithin, immunohistochemical approaches (CD3, CD20, Ki-67), and morphometrical techniques.
  • Density of immune cells and vascular structures compared between seasons.
  • Summer samples showed increased thickness of the splenic capsule and higher lymphocyte density (p < 0.05).
  • CD3-positive T lymphocytes significantly increased in the periarteriolar lymphoid sheath during summer.
  • Ki-67 immunoreactivity indicated heightened proliferative activity in germinal centers in summer (p < 0.05).
