The mechanisms for dominant T15 idiotype selection are not well understood, yet the significance of idiotypic regulation has been suggested. We proposed that to become dominant V regions of a given subset of B-1a cell must establish a functional idiotypic network with complementary T cells. Features required for the cells involved in immune network and steps preceding the establishment of clonal dominance...
Twenty-five V3 loops of envelope gp 120 extracted from 30 HIV-1 isolates were compared with T-cell receptor (TCR) subunits variable (V) portions using pairwise alignments of 11-residue peptides. The results indicate that, in comparison with random sequences, the analyzed V3 loops, unlike control (unrelated) sequences, display highly significant local similarity with TCR V δ (p 10 -...
