Systemic Autoimmunity Remodels Microbiota-Reactive CD4⁺ T Cell Immunity

Maricielo Vaella-Alarcon, Miki Kume, Silvia R. Davila-Paico, Luis F. Soto, Katherine S Saldana-Morales, Gillian L. McClennen, Jin Din, Samantha C. St. Jean, Daniel F. Zegarra-Ruiz

This study shows systemic autoimmunity expands and differentiates microbiota-reactive CD4 T cells, which exacerbate autoimmunity through IL-21 and IFN-gamma mechanisms.

TLR7-Dependent Autoimmunity Remodels Intestinal Immune Cell Dissemination

Katherine S Saldana-Morales, Miki Kume, Silvia R. Davila-Paico, Maricielo Vaella-Alarcon, Olivia Bache, Daniel F. Zegarra-Ruiz

This study shows that TLR7-dependent autoimmunity alters intestinal immune cell dissemination, reducing lymphocytes and increasing myeloid cells, especially dendritic cells, in gut and systemic tissues.
