Development of the Bursa of Fabricius in the Partridge and Pheasant

Poultry Science, 1987
Development and regression of the bursa of Fabricius was measured in chukar partridge (Alectoris chukar) and ring-necked pheasant (Phasianus colchicus) from hatch to 40 and 34 weeks of age, respectively. Testes weights were recorded for 8 to 34-week-old pheasants and 12 to 30-week-old chukars.

Beyond FoxP3—Identification of a Chicken Regulatory T Cell Signature

European Journal of Immunology, Volume 55, Issue 12, December 2025.
Chicken FOXP3+ putative regulatory T cells were identified using both bulk and single‐cell RNA sequencing to define their transcriptional signature and flow cytometry to confirm surface marker expression. This combined approach revealed a distinct putative Treg subset characterized by CD4, CD25, and GITR surface expression. ABSTRACT Regulatory T cells (
