This report describes an effective method for the cloning of Mycobacterium leprae-reactive T lymphocytes with Epstein-Barr-virus transformed autologous B cells as antigen-presenting cells. The two advantages of this method are that it drastically reduces the number of autologous peripheral blood mononuclear cells (< 107 cells) needed to obtain and propagate these T-cell clones (TLC), and that enables us to expand individual TLC to large numbers of cells (> 108). Thus the major obstacles for the cloning of T lymphocytes-especially important with regard to patients-are bypassed. Thus far, TLC from three leprosy patients have been established. These TLC are HLA class II restricted in their M. leprae-directed response. A marked enhancement in antigen responsiveness was observed after further expansion of several strikingly different antigen recognition patterns when tested against a number of other mycobacterial antigens; one TLC so far recognizes only M. leprae antigens.
