Interactions between pairs of membrane-bound receptors can enhance tumour development with implications for targeted therapies for cancer. Here we demonstrate clear heterotypic interaction between CD74 and CD44, which might act in synergy and hence contribute to breast cancer progression. CD74, a type II transmembrane glycoprotein, is a chaperone for MHC class II biosynthesis and a receptor for...
Background MIF via its receptor, CD74, initiates a signaling cascade that leads to proliferation and survival of cells. Also, MIF binding to CD74 activates p38 signaling pathways that lead to positive effect on the expression of COX-2. The aim of this study was to evaluate the gene expression profile of MIF, CD74 and COX-2 in normal, ectopic and eutopic endometrium during menstrual cycle. The e...
CD74 (invariant chain, li) is most renowned for its role in preparing major histocompatibility complex (MHC) class II molecules for peptide presentation to CD4þ T helper cells.1,2 Although we have known for some time that various CD74 isoforms exist, so far attempts to attribute distinct functions to each isoform have failed.3 The humanspecific CD74 isoform called p35 contains a retention motif...
CD74 is an integral membrane protein that was thought to function mainly as an MHC class II chaperone. However, CD74 was recently shown to have a role as an accessory-signaling molecule. Our studies demonstrated that CD74 regulates B-cell differentiation by inducing a pathway leading to the activation of transcription mediated by the NF-kappaB p65/RelA homodimer and its coactivator, TAF(II)105....
Cluster of differentiation 74 (CD74), a transmembrane glycoprotein, has been previously reported to be important in the pathogenesis of several cancers, including hematological malignancies and solid tumors. The present study analyzed the significance of CD74 in gallbladder carcinomas (GBCs) and indicated the correlation of CD74 expression with epithelial growth factor receptor levels. Immunohi...
Background—Adaptive immunity and innate immunity play important roles in atherogenesis. Invariant chain (CD74) mediates antigen-presenting cell antigen presentation and T-cell activation. This study tested the hypothesis that CD74-deficient mice have reduced numbers of active T cells and resist atherogenesis. Methods and Results—In low-density lipoprotein receptor– deficient (Ldlr / ) mice, CD7...
For more than 15 years, the tautomerase active site of macrophage migration inhibitory factor (MIF) and its catalytic residue Pro1 have been being targeted for the development of therapeutics that block activation of its cell surface receptor, CD74. Neither the biological role of the MIF catalytic site nor the mechanistic details of CD74 activation are well understood. The inherently unstable s...
Although metabolic derangement plays a central role in diabetic nephropathy, a better understanding of secondary mediators of injury may lead to new therapeutic strategies. Expression of macrophage migration inhibitory factor (MIF) is increased in experimental diabetic nephropathy, and increased tubulointerstitial mRNA expression of its receptor, CD74, has been observed in human diabetic nephro...
Modulation of the amyloid-β (Aβ) trafficking pathway heralds a new therapeutic frontier for Alzheimer's disease (AD). As CD74 binds to the amyloid-β precursor protein (APP) and can suppresses Aβ processing, we investigated whether recombinant adeno-associated virus (AAV) delivery of CD74 could reduce Aβ production and affect disease outcomes. This idea was tested in a mouse AD model. Cotransduc...

This study tested the hypothesis that CD74-deficient mice have reduced numbers of active T cells and resist atherogenesis. METHODS AND RESULTS In low-density lipoprotein receptor-deficient (Ldlr(-/-)) mice, ...
