The development of reagents against leukocyte differentiation antigens in veterinary species is delayed compared to mouse and men and therefore also the number of existing reagents for the characterisation of leukocytes derived from species with importance in veterinary medicine is restricted. Cross-reactive studies with existing well defined monoclonal antibodies directed against leukocyte differentiation antigens derived from other species are an alternative approach to enhance the panel of reagents in veterinary immunology. This study describes the activities of the animal homologue section in frame of human leukocyte differentiation antigen 8-workshop (HLDA8) were 376 monoclonal antibodies, mainly directed against human leukocytes had been tested for their reactivity with 17 different animal species including non-human primates, ruminants, swine, horse, carnivores, rabbit, guinea pig, chicken and fish. In a first round 182 mAb were selected based on there reactivity in FCM analyses with at least one species for further studies, including multi-colour FCM, and molecular analyses of the antigens. Interesting was the species-overlapping reactivity of mAb directed against distinct clusters: 11 out of 17 species reacted with CD9, 11 of 17 with CD11a, CD14 (11/17), CD18 (13/17), CD21 (7/17), CD29 (10/17), CD44 (13/17), CD45 (9/17), CD47 (10/17), CD49d (13/17), CD61 (6/17), CD86 (7/17), CD91 (5/17), and CD172a (10/17), indicating evolutionary highly conserved epitopes on these surface molecules. Our results suggest the suitability of cross-reactive mAb for the animal model studies. Moreover, these findings contribute to our understanding of the evolution of the immune system.
