Explanation:
Detailed explanation-1: -Linear epitopes are recognized by T cells. Often, these epitopes are internal hydrophobic amino acid sequences processed by macrophages and presented to T cells in the context of human leukocyte antigen (HLA) class I and class II molecules.
Detailed explanation-2: -T-cell epitope recognition. T-cell epitopes are peptides derived from antigens and recognized by the T-cell receptor (TCR) when bound to MHC molecules displayed on the cell surface of APCs. (a) CD4 T-cells express the CD4 coreceptor, which binds to MHC II, and recognize peptides presented by MHC II molecules.
