{"doi":"10.1126/sciadv.adp2636","title":"CD4 <sup>+</sup> and CD8 <sup>+</sup> T cells are required to prevent SARS-CoV-2 persistence in the nasal compartment","abstract":"SARS-CoV-2 infection induces the generation of virus-specific CD4 + and CD8 + effector and memory T cells. However, the contribution of T cells in controlling SARS-CoV-2 during infection is not well understood. Following infection of C57BL/6 mice, SARS-CoV-2–specific CD4 + and CD8 + T cells are recruited to the respiratory tract, and a vast proportion secrete the cytotoxic molecule granzyme B. Using depleting antibodies, we found that T cells within the lungs play a minimal role in viral control, and viral clearance occurs in the absence of both CD4 + and CD8 + T cells through 28 days postinfection. In the nasal compartment, depletion of both CD4 + and CD8 + T cells, but not individually, results in persistent, culturable virus replicating in the nasal epithelial layer through 28 days postinfection. Viral sequencing analysis revealed adapted mutations across the SARS-CoV-2 genome, including a large deletion in ORF6. Overall, our findings highlight the importance of T cells in controlling virus replication within the respiratory tract during SARS-CoV-2 infection.","journal":"Science Advances","year":2024,"id":425661,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":19,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9448,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1063514,"name":"Katherine Johnson","orcid":"0000-0002-9226-0672","position":1,"is_corresponding":false},{"id":106936,"name":"Abigail Vanderheiden","orcid":"0000-0003-1321-4510","position":2,"is_corresponding":false},{"id":369206,"name":"Elizabeth J.
