Background: Leprosy is a debilitating infectious disease of human skin and nerves. Genetics factors of the host play an important role in the disease susceptibility. Toll-interacting protein (TOLLIP) is an inhibitory adaptor protein within the toll-like receptor (TLR) pathway, which recognizes structurally conserved molecular patterns of microbial pathogens, initiating immune responses. The objective of this study was to investigate the association of variants in the TOLLIP gene with susceptibility to leprosy in Mexican patients.
Methods: TOLLIP polymorphisms were studied using a case-control design of Mexican patients with lepromatous leprosy (LL). The polymorphisms of TOLLIP at loci -526 C>G (rs5743854), 1309956C>T (rs3750920), 1298430C>A (rs5744015), and 1292831 G>A (rs3750919) were analyzed by PCR, with sequence-specific primers in LL patients and healthy subjects (HS) as controls.
Results: Genotype distributions were in Hardy Weinberg equilibrium for all sites except for rs3750920. Neither genotype nor allele frequencies were statistically different between LL patients and controls (P > 0.05). The maximum pairwise D' coefficient reached was 0.44 of linkage (P = 0.01) for all the polymorphisms except for rs5743854. The three loci haplotype comparison yielded no significant differences between groups.
Conclusions: Just the individuals with genotype C/C of rs3750920 have a trend of protective effect to developing LL.

Background: Lung cancer is a life-threatening disease that occurs worldwide, but is especially common in China. The crucial role of the tumour microenvironment (TME) in non-small cell lung cancer (NSCLC) has attracted recent attention. Cancer-associated fibroblasts (CAFs) are the main factors that contribute to the TME function, and CAF exosomes are closely linked to NSCLC.

Background: Genetic polymorphisms in Toll-interacting protein (TOLLIP) have been documented in relation to clinical manifestations of interstitial lung disease (ILD). Nevertheless, the findings across studies present inconsistencies. The present meta-analysis endeavors to elucidate the nexus between genetic variations in TOLLIP and the onset and prognosis of interstitial lung disease (ILD), with the overarching aim of providing insight into the pathophysiological underpinnings of ILD.

Article Synopsis
- MAVS is a key player in the body's antiviral immune response, and its regulation is essential for maintaining immune balance.
- The study discovered that a new protein in ducks, ApdTRIM13, negatively regulates MAVS by targeting it for degradation during RNA virus infections.
- The process involves another protein, ApdSQSTM1, which helps ApdTRIM13 deliver MAVS to cellular structures for degradation, highlighting a unique mechanism linking autophagy and immune responses in birds.

Article Synopsis
- Lactiplantibacillus species, particularly strains MKMB01 and MKMB02, show promise as probiotics that help regulate the immune response against enteric pathogens like Salmonella enterica typhimurium.
- The study utilized various cell lines and techniques, including qRT-PCR and electron microscopy, to assess the probiotics' effects on immune responses and gut integrity.
- Results indicated that both strains enhanced gut health and reduced inflammation by maintaining tight junction proteins and downregulating pro-inflammatory cytokines, while also improving mitochondrial function impaired by Salmonella.
