Osteopontin neutralization increases vitamin D receptors on NKT cells and ameliorates liver fibrosis by promoting their activity.

Introduction And Aims: Vitamin D has an immunomodulatory property influencing the activity of NKT cells. We aimed to study the impact of osteopontin (OPN), a key driver of fibrosis, on NKT cells' vitamin D receptor (VDR) and activity alterations.

Methods: Liver fibrosis was induced in BALB/C mice with carbon-tetrachloride (CCl) for 8 weeks with either vitamin D [100 ng/kg] or InVivoMAb anti-mouse OPN [100 μg/kg] 2X/week started at week-4 of CCl The liver injury profile of serum ALT, AST, and inflammatory cytokines were evaluated.

Novel Immunological Markers of Intestinal Impairment Indicative of HIV-1 Status and/or Subclinical Atherosclerosis.

Antiretroviral therapy (ART) controls HIV-1 replication in people with HIV-1 (PWH), but immunological restauration at mucosal barrier surfaces is not achieved. This fuels microbial translocation, chronic immune activation, and increased comorbidities, including cardiovascular disease (CVD). Here, we sought to identify novel markers of mucosal barrier impairment in the blood to predict the HIV and/or CVD status.

A mother-child data linkage approach using data from the information system for the development of research in primary care (SIDIAP) in Catalonia.

Background: Large-scale clinical databases containing routinely collected electronic health records (EHRs) data are a valuable source of information for research studies. For example, they can be used in pharmacoepidemiology studies to evaluate the effects of maternal medication exposure on neonatal and pediatric outcomes. Yet, this type of studies is infeasible without proper mother-child linkage.
