A team led by Scott Boyd, from the Stanford University School of Medicine, USA, analyzed 12 samples of umbilical cord tissue and blood from 93 children aged 1 to 3, as well as blood samples from 114 adults of various ages and eight blood and tissue samples from eight deceased adults (<em>Science<\/em>, April 12). The researchers tested the capacity of B lymphocyte immune cells to recognize a number of pathogens. They found a much higher frequency of B lymphocytes capable of reacting to the SARS-CoV-2 virus in the samples from children. The hypothesis is that more recent exposure to other coronaviruses among children allows their immune systems to better identify SARS-Cov-2, while adult B lymphocytes have already lost the ability to deal with this type of infection.<\/p>\n","protected":false},"excerpt":{"rendered":"Studies of blood and tissue samples taken before the COVID-19 pandemic may help explain why the disease is more common and more severe in adults than in children","protected":false},"author":475,"featured_media":400667,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[210,242,260],"coauthors":[785],"class_list":["post-397799","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-cellular-biology","tag-immunology","tag-public-health","keywords-coronavirus-en","keywords-covid-19-en","keywords-sars-cov-2-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/397799","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=397799"}],"version-history":[{"count":2,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/397799\/revisions"}],"predecessor-version":[{"id":401073,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/397799\/revisions\/401073"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/400667"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=397799"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=397799"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=397799"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=397799"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
