Immunometabolic Activation of Invariant Natural Killer T Cells
Frontiers in Immunology, 2018 Invariant natural killer T (iNKT) cells are lipid-reactive T cells with profound immunomodulatory potential. They are unique in their restriction to lipid antigens presented in CD1d molecules, which underlies their role in lipid-driven disorders such as ...

Systems Biology and Pangenome of Salmonella O-Antigens. [PDF]
, 2019 O-antigens are glycopolymers in lipopolysaccharides expressed on the cell surface of Gram-negative bacteria. Variability in the O-antigen structure constitutes the basis for the establishment of the serotyping schema. We pursued a two-pronged approach to

CD1-Restricted T Cells at the Crossroad of Innate and Adaptive Immunity
Journal of Immunology Research, 2016 Lipid-specific T cells comprise a group of T cells that recognize lipids bound to the MHC class I-like CD1 molecules. There are four isoforms of CD1 that are expressed at the surface of antigen presenting cells and therefore capable of presenting lipid ...

Deficiency of RgpG causes major defects in cell division and biofilm formation, and deficiency of LytR-CpsAPsr family proteins leads to accumulation of cell wall antigens in culture medium by Streptococcus mutans [PDF]
, 2017 Streptococcus mutans is known to possess rhamnose-glucose polysaccharide (RGP), a major cell wall antigen. S. mutans strains deficient in rgpG , encoding the first enzyme of the RGP biosynthesis

Antigenic heterogeneity of lipid A of Haemophilus influenzae [PDF]
Infection and Immunity, 1985 The chemical structure and biologic function of the lipid A portion of lipopolysaccharide are not identical among gram-negative bacteria. This study indicates that antigenically heterogeneous lipid A exists among strains of Haemophilus influenzae. An immunoglobulin G3 murine monoclonal antibody, 3D2, produced against a nontypable H.

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment
Aging and Cancer, EarlyView.Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

A T-cell receptor escape channel allows broad T-cell response to CD1b and membrane phospholipids
Nature Communications, 2019 CD1 proteins present lipid antigens to T cells via the T cell receptor. Here the authors describe T cell reactivity to human membrane lipid moieties and provide structural data to define a molecular mechanism of promiscuous recognition of self-derived ...
