摘要：

CD40 is mainly expressed by professional antigen-presenting cells (APCs). Its ligand,CD40L, is transiently expressed on activated CD4(+) T-cells. CD40-CD40L interactions mediate T-cell help to APCs and provide crucial signals for affinity maturation and B-cell class switching. In mammals, agonistic monoclonal anti-CD40 antibodies (mAbs) mimic the effects of CD40L on APCs, leading to enhanced T-cell priming and expansion, increased antibody production and class switching. In this study, we describe agonistic anti-chicken CD40 mAb 2C5. This mAb detected CD40 on primary chicken B-cells and macrophages. DT40 B-cells, and HD11 macrophages, induced NO synthesis in HD11 macrophages, and stimulated DT40 B-cell proliferation. These observations demonstrated at least partial functional equivalence of 2C5 to chicken CD154. This mAb may therefore constitute a new tool to study the role of CD40 in the chicken immune system, and its agonistic effects suggest that it could also be used as an adjuvant.
