Adaptive immune response of identical twins to live vaccine
T-cell receptors (TCRs) play a key role in adaptive immunity. TCR repertoire is very diverse and unique to each individual because it forms in the stochastic DNA recombination process. The group of scientists from the Department of genomics of adaptive immunity in collaboration with ENS (Paris, France) studied TCR repertoires of identical twins after immunization with a live vaccine. In each donor, they identified about a thousand different T-cell clones responding to immunization. Responding clones have almost unique repertoire in each donor with higher overlap in identical twin pairs. The study was supported by RSF and published in Proceedings of the National Academy of Sciences.
