Background: The vitamin D pathway contributes to the microbicidal activity of macrophages against infection. In addition to induction of this pathway, interferon-gamma (IFNγ), interleukin (IL)-15, and IL32γ are part of a network of pro-inflammatory cytokines. The aim of this study was to evaluate single-nucleotide polymorphisms (SNPs) in the components of the vitamin D pathway and associated cytokine genes that could be related to resistance or susceptibility to American tegumentary leishmaniasis (ATL).

The therapeutic effects of probiotics in patients with traumatic brain injury (TBI) remain unclear. This study aimed to investigate the effects of probiotic supplementation on cell adhesion molecules, oxidative stress, and antioxidant parameters in TBI patients. This randomized, double-blind, placebo-controlled trial included 46 TBI patients who were randomly assigned to receive either a probiotic supplement (n = 23) or a placebo (n = 23) for 14 days.

There is little research on anemia and vitamin D deficiency in HIV-exposed uninfected (HEU) children. This study was aimed to describe and compare the prevalence of anemia and vitamin D inadequacy in HEU children and HIV-unexposed uninfected (HUU) children, and to examine the associations of HIV exposure with anemia and vitamin D inadequacy. This was a hospital-based descriptive cross-sectional study nested within the Prevention of Mother-to-Child Transmission (PMTCT) of HIV program in Hunan Province during July and September 2022.

Vitamin D receptor (VDR) plays a critical role in regulating multiple biological processes, including bone metabolism and cell differentiation, by mediating transcriptional activation in response to ligand binding. We have constructed an environmentally fluorescent probe 2 for VDR to facilitate real-time observation of its ligand-dependent conformational changes in living cells. This probe 2 was synthesized by introducing a dansyl fluorophore via an ethynyl group at the C11 position of 1α,25(OH)2D3.
