Cytolytic T lymphocytes (CTL) 1 recognize a wide variety of antigens cross-reacting with those against which the immune population was originally sensitized (1). Definitive analysis of this cross-reactivity requires examination of the killing specificity

Definitive analysis of this cross-reactivity requires examination of the killing specificity exhibited by CTL at the single-cell level rather than at the population level. Such an examination would… CONTINUE READING
