Summary: The study revealed that Dectin-1 can effectively control TSLP-induced Th2-type immune responses by reducing the expression of OX40L and CCL17. Experimental results showed that Dectin-1 activation can suppress allergic reactions and allergen-specific immune responses in both ex vivo and in vivo settings.

Summary: This study characterized RelB-deficient autoimmunity by transcriptomic profiling and found that loss of RelB leads to excessive induction of interferon-stimulated genes and suppression of inflammatory response genes. The genetic evidence also suggests that the autoimmune pathology in RelB-deficient mice is independent of interferon.

Summary: The use of a pseudotyped viral vector has successfully enabled genetic manipulation of parasitic nematodes, including gene silencing and expression of exogenous genes. This method holds promise for advancing research on the complex biology of nematode parasites and identifying new targets for infection control.

Summary: Lentiviral vectors are highly effective for vaccination, especially in transducing dendritic cells and activating naive T cells. They induce endogenous expression of transgenic antigens and stimulate strong and long-lasting immunity. Lentiviral vectors have low pro-inflammatory properties and can be used for mucosal vaccination. This review summarizes the immunological aspects, optimization for CD4(+) T cell induction, and recent data on lentiviral vector-based vaccination in preclinical models for various infectious diseases including flaviviruses, SARS-CoV-2, and Mycobacterium tuberculosis.

Summary: Limbal stem cell transplantation is an efficient treatment for LSC deficiency, with HLA variability posing a challenge for allogeneic graft survival. A genetic engineering strategy was proposed to reduce LSC immunogenicity, resulting in decreased T cell activation and improved survival potential post-transplantation.

Summary: This study reports the design and production of a lentiviral vector that incorporates two functionally independent promoters, allowing for the expression of a tumour-directed receptor and inducible gene in T cells. The vector enables the delivery of various genes to human T cells, improving the safety and efficacy of T-cell therapies.

Summary: Deletion of ADAR1 in CD11c+ APCs leads to changes in immune response, including enrichment of inflammatory cells, increased activated tissue resident memory T cells, and broad changes in antiviral transcriptional signature. These changes can be partially reversed by blocking IFNAR1 signaling and promote early resistance against SARS-CoV-2 infection.

Summary: In this study, a HuAd5 vector encoding shRNA was shown to effectively suppress the replication of all four prototypic DENV serotypes in Vero cells and human macrophages. The HuAd5 vector-mediated DENV suppression in macrophages was found to be dependent on the presence of anti-HuAd5 antibodies, suggesting implications for the specific targeting of HuAd5 vector-mediated antiviral RNA interference therapy to macrophages.
