Measles live attenuated vaccine (MV) induces strong humoral and cellular systemic memory responses allowing the successful control of measles since decades. MV has also been adapted into a promising platform with several candidates in clinical development. To understand document tissue-scaled response induced by MV, we explored specific induction persistence resident T cells (Trm) lungs liver, two critical targeted tissues for development against diseases. Trm are subset non-circulating highly specialized cells. They found at multiple barrier mucosal sites, conveniently positioned to rapidly react pathogens. The different is therefore We demonstrated mice rapid generation MV-specific vectorized antigen-specific liver after single dose, whatever route immunization. intranasal more than other routes, confirming potential administration replicative viral vectors generate pulmonary immune response. were functionally active, CD8+ secreting granzyme B upon vitro restimulation CD4+ IFN-γ TNF-α. confirmed human lymphocytes this tissue tropism showing an overexpression homing receptors directing them epithelial inflamed tissues.

Cross-reactive αβ T cell receptors (TCRs) recognizing multiple peptide variants can provide effective control of rapidly evolving viruses yet remain understudied. By screening 12 naturally occurring influenza-derived HLA-B*35:01–restricted nucleoprotein (NP) 418–426 epitopes (B*35:01-NP 418 ) that emerged since 1918 within influenza A viruses, including 2024 A/H5N1 we identified functional broadly cross-reactive cells universally NP variants. Binding studies demonstrated TCR cross-reactivity was concomitant with diminished antigen sensitivity. Primary human B*35:01/NP + CD8 lines displayed reduced in the absence coreceptor binding, validating low avidity B*35:01-NP responses. Six TCR–HLA-B*35:01/NP crystal structures showed how TCRs recognized epitope Specific interactions were formed invariant and conserved peptide-HLA features, thus remaining distal from highly varied positions epitope. Our study defines molecular mechanisms associated extensive toward viral relevant to universal protective immunity against influenza.

NF-κB is a crucial transcription factor in lymphocyte signaling. It activated by environmental cues that drive differentiation to combat infections and cancer. As key player inflammation, also significantly impacts autoimmunity transplant rejection, making it an important therapeutic target. While the signaling molecules regulating this pathway are well-studied, effect of changes levels on T differentiation, fate, function not fully understood. Advances computational biology new NF-κB-inducible animal models beginning clarify these questions. In review, we highlight recent findings related cells, focusing how affecting determine cell fate function.

Intranasal vaccines potentially offer superior protection against viral infections compared with injectable vaccines. The immunogenicity of intranasal including adenovirus vector (AdV), has room for improvement, while few options are available safe execution. In this study, we demonstrate that modifying a basic parameter vaccine formulation, i.e., osmolarity, can significantly enhance the Addition glycerol to AdV solutions, unlike other viscous additives, enhanced systemic and mucosal antibodies as well resident memory T cells in nasal tissues, which could protect tissue lungs influenza virus.
