Early investigation revealed a reduced risk of SARS-CoV-2 infection among social contacts of COVID-19 vaccinated individuals, referred to as indirect protection. However, indirect protection from SARS-CoV-2 infection-acquired immunity and its comparative strength and durability to vaccine-derived indirect protection in the current epidemiologic context of high levels of vaccination, prior infection, and novel variants are not well characterized. Here, we show that both vaccine-derived and infection-acquired immunity independently yield indirect protection to close social contacts with key differences in their strength and waning.

Autoimmune liver diseases (AILD) involve dysregulated CD4 T cell responses against liver self-antigens, but how these autoreactive T cells relate to liver tissue pathology remains unclear. Here we perform single-cell transcriptomic and T cell receptor analyses of circulating, self-antigen-specific CD4 T cells from patients with AILD and identify a subset of liver-autoreactive CD4 T cells with a distinct B-helper transcriptional profile characterized by PD-1, TIGIT and HLA-DR expression. These cells share clonal relationships with expanded intrahepatic T cells and exhibit transcriptional signatures overlapping with tissue-resident T cells in chronically inflamed environments.

Epstein-Barr virus-associated smooth muscle tumors (EBV-SMTs) represent a rare category of soft tissue tumors that are predominantly seen in individuals with compromised immune systems. Pathologically, EBV-SMT has malignant potential because of its unpredictable nature. These tumors can manifest at various anatomical sites or even multiple lesions in different locations.

Immune thrombocytopenic purpura (ITP) is an acquired immune-mediated bleeding disorder characterized by isolated low platelet (PLT) counts. Immune thrombocytopenic purpura pathogenesis involves multiple immune mechanisms causing PLT destruction and inadequate production. Owing to impaired immune homeostasis, ITP patients can develop other than anti-PLT autoantibodies even in the absence of clinical signs of autoimmune disease, such as anti-thyroglobulin (TG) and anti-thyroperoxidase (TPO) antibodies.

Problem: Oxidative stress (OS) plays a key role in the pathogenesis of gestational diabetes mellitus (GDM), but it was not well understood. We aimed to investigate the biomarkers and underlying mechanisms of OS-related genes in GDM.
Method Of Study: The GSE103552 and GSE70493 datasets of GDM were acquired from the Gene Expression Omnibus (GEO) database.
