Abstract

Keyhole-limpet-hemocyanin-specific I-A(d)-restricted T helper cells type 1 (T(H1) cells) and type 2 (T(H2) cells) were studied for their ability to physically conjugate to trinitrophenyl-specific antigen-binding B cells (TNP-ABCs). The same TNP-ABCs (which had already processed TNP-keyhole limpet hemocyanin) formed conjugates with one or the other T helper (T(H)) cell type, and conjugation was antigen-specific and major histocompatibility complex-restricted. The conjugation of a fixed number of one type of T(H) cell to the TNP-ABCs was inhibited by co-incubation with increasing numbers of cells of the other T(H) cell type. Thus, the vast majority of TNP-ABCs can conjugate to either type of T(H) cell. A similar pattern of inhibition of the conjugation of one T(H) cell type to the TNP-ABCs was seen when cells were co-incubated with increasing numbers of cells from an alloreactive T-cell clone. In all cases, conjugates contained only one T cell bound to one B cell, suggesting that interaction of an antigen-presenting B cell with one T(H) cell prevents the simultaneous binding of another T(H) cell.
