the autospecific t cell clones also responded to murine l cell transfectants expressing dr alpha dr1 beta as well as to transfectants expressing the mouse/human hybrid mhc molecule i-e alpha dr1 beta but not to the reciprocal combination dr alpha i-e beta , thus confirming the importance of the beta 1 domain to t cell recognition .
