The pathogenesis of MAKI is not completely understood but some hypotheses are well recognized. Host\u2013parasite interactions lead to mechanical obstruction, disorders in the renal microcirculation, and immune-mediated glomerular injury. We investigated the influence of CD8\u207a T cells in the pathogenesis of malaria-induced renal disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      To assess the role of T lymphocytes in MAKI pathogenesis, we used adoptive transfer; antibody-driven CD8\n                      <jats:sup>+<\/jats:sup>\n                      T cells depletion and treatment with FYT720.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The transference of total T cells isolated from malaria-infected donor mice into naive recipient animals reproduced kidney tubule-interstitial damage without affecting glomerular function. It was associated with increased accumulation of CD8\n                      <jats:sup>+<\/jats:sup>\n                      T cells in the kidneys of recipient mice.

Finally, we evaluated FTY720, an immunomodulatory drug that sequesters T cells in lymphoid organs and limits their migration, as a potential therapeutic strategy. Treatment with FTY720 prevented the development of proteinuria and the increase in the urine to creatinine ratio. Moreover, FTY720 reduced urinary \u03b3-glutamyl transferase (\u03b3-GT) levels, a marker of tubular injury, but did not alter plasma urea and creatinine, two markers of glomerular function.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>\n                      Our results add new knowledge demonstrating that CD8\n                      <jats:sup>+<\/jats:sup>\n                      T cells have a specific role in tubule-interstitial injury pathology during MAKI.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fcimb.2025.1561806","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T06:49:21Z","timestamp":1751266161000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["CD8+ T cells promote tubule-interstitial damage in malaria-induced acute kidney injury"],"prefix":"10.3389","volume":"15","author":[{"given":"Douglas Esteves","family":"Teixeira","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah Aparecida dos Santos","family":"Alves","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro S\u00e1","family":"Pinheiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leandro Souza","family":"Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo Pacheco","family":"Silva-Aguiar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diogo Barros","family":"Peruchetti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatiana Almeida","family":"P\u00e1dua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana Concei\u00e7\u00e3o","family":"Souza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celso","family":"Caruso-Neves","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Acacia S\u00e1","family":"Pinheiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,6,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e93634","DOI":"10.1371\/journal.pone.0093634","article-title":"Mice Rescued from Severe Malaria Are Protected against Renal Injury during a Second Kidney Insult","volume":"9","author":"Abreu","year":"2014","journal-title":"PloS One"},{"key":"B2","doi-asserted-by":"publisher","first-page":"10910","DOI":"10.1038\/s41598-018-29355-0","article-title":"Characterization of the effects of immunomodulatory drug fingolimod (FTY720) on human T cell receptor signaling pathways","volume":"8","author":"Baer","year":"2018","journal-title":"Sci.
