{"doi":"10.17615/y4yj-ah33","title":"Regulatory T Cell Induction and Retention in the Lungs Drives Suppression of Detrimental Type 2 Th Cells During Pulmonary Cryptococcal Infection","abstract":"Lethal disease caused by the fungus, Cryptococcus neoformans, is a consequence of the combined failure to control pulmonary fungal replication and immunopathology caused by induced type-2 helper T (Th2) cell responses in animal models. In order to gain incites into immune regulatory networks, we examined the role of regulatory T (Treg) cells in suppression of Th2 cells, using a mouse model of experimental cryptococcosis. Upon pulmonary infection with Cryptococcus, Treg cells accumulated in the lung parenchyma independently of priming in the draining lymph node. Using peptide-MHCII molecules to identify Cryptococcus-specific Treg cells combined with genetic fate-mapping, we noted that a majority of the Treg cells found in the lungs were induced during the infection. Additionally, we found that Treg cells utilized the transcription factor, Interferon Regulatory Factor 4 (IRF4), to dampen harmful Th2 cell responses, as well as mediate chemokine retention of Treg cells in the lungs. Taken together, induction and IRF4-dependent localization of Treg cells in the lungs allow Treg cells to suppress the deleterious effects of Th2 cells during cryptococcal infection.","journal":"UNC Libraries","year":2020,"id":143453,"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":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.953,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":542896,"name":"Kirsten Vang Nielsen","orcid":"0000-0001-7956-1748","position":1,"is_corresponding":false},{"id":461755,"name":"Kyle D.
