Markers of T-cell differentiation and maturation in C57BL/6 and BALB/c mice and in the calf: a comparative study.
No significant differences were found between C57BL/6 and BALB/c mice in the levels of Thy 1.2 antigen (a T-cell marker) or the activities of the T-cell maturation-related enzymes adenosine deaminase (ADA, EC 3.5.4.4), serine-esterase (SE, EC 3.4.21), N-acetyl-beta-D-glucosaminidase (NABG, EC 3.2.1.30) and beta-glucuronidase (BG, EC 3.1.1.1), in either unfractionated lymphoid cells or T-lymphocyte-enriched fractions. ADA, SE, NABG and BG activities were much higher (P < 0.01) in the calf than in the corresponding populations in mice. However, the distributions of these activities among thymocyte subpopulations were very similar in mice and the calf. These results provide indirect evidence to suggest that the course of T-cell maturation is similar in mice and the calf.
