These lymphocytes originate from bone marrow progenitor cells and migrate to the thymus for maturation, selection, and peripheral export. Peripheral T cells are subdivided into groups that include naïve T cells, which are capable of responding to new antigens, memory T cells derived from previous antigen activations and maintain long-term immunity, and regulatory T cells that coordinate the immune response (163).","tracks":[{"project":"LitCovid-sentences","denotations":[{"id":"T255","span":{"begin":0,"end":118},"obj":"Sentence"},{"id":"T256","span":{"begin":119,"end":256},"obj":"Sentence"},{"id":"T257","span":{"begin":257,"end":535},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T255","pred":"source","obj":"LitCovid-sentences"},{"subj":"T256","pred":"source","obj":"LitCovid-sentences"},{"subj":"T257","pred":"source","obj":"LitCovid-sentences"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"2010","span":{"begin":363,"end":365},"obj":"Gene"},{"id":"2011","span":{"begin":193,"end":195},"obj":"Gene"}],"attributes":[{"id":"A2010","pred":"tao:has_database_id","subj":"2010","obj":"Gene:6999"},{"id":"A2011","pred":"tao:has_database_id","subj":"2011","obj":"Gene:6999"},{"subj":"2010","pred":"source","obj":"LitCovid-PubTator"},{"subj":"2011","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-sentences","color":"#93ec93","default":true},{"id":"LitCovid-PubTator","color":"#ec93ad"}]}]}}
