Defining determinants of T cell fate is central to understanding adaptive immunity and the design of effective vaccines. Tubo et al. demonstrate that intrinsic properties of T cell receptor signaling dictate whether CD4 T cells adopt predominantly type 1 helper or follicular helper T cell phenotypes in response to bacterial or viral infection.
Sustained long-term antibody levels are the cornerstone of protective immunity, yet it remains unclear how they are durably maintained. A predominant theory implicates antigen-independent antibody production by a subset of long-lived plasma cells (LLPCs) that survive within bone marrow (BM). Central tenets of this model--that BM LLPCs constitute a subset defined by intrinsic biology distinct fr...
It is thought that cancer cells engage in Warburg metabolism to meet intrinsic biosynthetic requirements of cell growth and proliferation. Papers by Chang et al. and Ho et al. show that Warburg metabolism enables tumor cells to restrict glucose availability to T cells, suppressing anti-tumor immunity.
Tumor-intrinsic immuno-resistance is a prerequisite for emergence of follicular lymphomas. Here we show that in vitro, such cells are more resistant to immune cytolysis when grown as follicle-mimicking tridimensional aggregates than when grown as cell suspensions. So in patients, this innate adaptation to tumor immunity might precede its selective pressure.
INTRODUCTION Recombinant Newcastle Disease virus (rNDV) vectored vaccines are safe mucosal applicable vaccines with intrinsic immune-modulatory properties for the induction of efficient immunity. Like all viral vectored vaccines repeated inoculation via mucosal routes invariably results to immunity against viral vaccine vectors. To obviate immunity against viral vaccine vectors and improve the ...
The morphogenic role of retinoic acid (RA) in regulating immunity is underscored by our recent studies that show increased regional concentrations of RA and commensurate RA signaling in CD8+ T cells within the tumor microenvironment. This study demonstrated for the first time that intrinsic RA signaling is required for tumor associated antigen (TAA)-specific CD8+ T-cell survival and hence for t...
Primate genomes contain a large number of endogenous retroviruses and encode evolutionarily dynamic proteins that provide intrinsic immunity to retroviral infections. We report here the resurrection of the core protein of a 4-million-year-old endogenous virus from the chimpanzee genome and show that the human variant of the intrinsic immune protein TRIM5alpha can actively prevent infection by t...
PML nuclear bodies (PML-NBs) are enigmatic structures of the cell nucleus that act as key mediators of intrinsic immunity against viral pathogens. PML itself is a member of the E3-ligase TRIM family of proteins that regulates a variety of innate immune signaling pathways. Consequently, viruses have evolved effector proteins to modify PML-NBs; however, little is known concerning structure-functi...
