Persisting fetal clonotypes influence the structure and overlap of adult human T cell receptor repertoires

Abstract: The diversity of T-cell receptors recognizing foreign pathogens is generated through a highly stochastic recombination process, making the independent production of the same sequence rare. Yet unrelated individuals do share receptors, which together constitute a "public" repertoire of abundant clonotypes. The TCR repertoire is initially formed prenatally, when the enzyme inserting random nucleotides is downregulated, producing a limited diversity subset. By statistically analyzing deep sequencing T-cell repert… Show more

“…18, 2016; more than 17 years. Similarly, prenatally formed T-cell receptors shared by twins have been reported to have lifetimes > 30 years [31]. During suppressive ART the turnover of infected memory CD4 cell clones is likely to follow the same dynamics as in uninfected people.…”

“…Предположим, что мы рассматриваем определенный V -сегмент, ко-торый выровнялся на двенадцать нуклеотидных позиций. Он занимает четыре кодона со следующими граничными позициями на последовательности: [1,3], [4,6], [7,9], [10,12]. Предположим, что последние три нуклеотида (на десятой, одиннадцатой и двенадцатой позициях) этого сегмента это CTA, и предполо-жим, что эти три позиции соответствуют аминокислоте L (другими словами, в исходной аминокислотной последовательности рецептора, на который вырав-нивается этот V -сегмент, на четвертой позиции стоит L).…”
