在一项有助于科学家更好地了解有性生殖遗传基础的研究中,来自哥伦比亚大学内科和外科学院的研究人员首次识别出一个建立母系基因的基因组印记(Genomic imprinting)所必需的基因。 基因组印记是指生物体标记部分或全部继承自父本或者母本的遗传物质的过程。
Parent-specific gene expression (genomic imprinting) is an evolutionary puzzle because it forgoes an important advantage of diploidy — protection against the effects of deleterious recessive ...
Imprinting is a process in which the expression of each gene copy is determined by the sex of the parent. Not all genes go through imprinting, but for those that do, imprinting is required for ...
Genomic imprinting means that specific genes inherited from the mother or father are active, whilst the gene inherited from the other parent is inactive. This preferential expression of one allele ...
Does immune imprinting help to explain breakthrough infections? Most people in the industrialised world have been infected or vaccinated against Covid — or both.
What is original antigenic sin or immunological imprinting? "There's a theory that our immunological response to the first exposure to a virus may sort of imprint your immune system," said John ...
Immune imprinting refers to the way people’s immune systems respond to a newly circulating strain by producing antibodies tailored to the first strain they encountered.
Imprinting, seen after the Russian pandemic of 1889 and others, needs to be in the discussion of Covid-19 vaccines for infants and toddlers.
