In addition, the researchers found that “cross-reactive” T cells—those made during infection with other coronaviruses that can cause the common cold—enhanced the vaccine response. WebT-cell cross-reactivity is a phenomenon of the immune system defined as the recognition of two or more peptide-MHC complexes (pMHCs) by the TCR. The recognition is based on the ability of the TCR to bind sufficiently well to initiate a cellular response. space suit genesis 3 female breast cleavage
