Observations on T-cell sub-populations in type II reactions.

15 cases each of Type II Reaction, LL and TT Leprosy and 50 endemic controls were studied for phenotypic markers T2, T4 and T8 by 2 step immunoperoxidase technique. There was statistically significant increase in T4 (helper) cells in Type II Reaction. There was also a decrease in T8 cells but this was not statistically significant.
