    Mast Cell Infiltration of the Choroid and Protease Release Are Early Events in Age-Related Macular Degeneration Associated with Genetic Risk at Both Chromosomes 1q32 and 10q26

    Investigators found that increased mast cell infiltration of the inner choroid, degranulation, and subsequent extracellular matrix remodeling were early events in age-related macular degeneration (AMD) pathogenesis and represented a unifying mechanistic link between chromosome (Chr)1- and Chr10-mediated AMD.

    Loss of T Cell Tolerance in the Skin Following Immunopathology Is Linked to Failed Restoration of the Dermal Niche by Recruited Macrophages

    Researchers demonstrated that pathology initiated dermis-specific macrophage differentiation and showed that acute graft-versus-host disease-primed macrophages continued to dominate the dermal compartment at the relative expense of quiescent MHCIIint cells.

    Olfactory Receptor OR2H1 Is an Effective Target for CAR T Cells in Human Epithelial Tumors

    Recombinant OR2H1 IgG generated with the VH/VL sequences of a CAR construct specifically detected OR2H1 protein signal in 60 human lung cancers, 40 ovarian carcinomas and 73 cholangiocarcinomas, at positivity rates comparable to mRNA expression and without OR2H1 staining in 58 normal tissues.
