HLA-DRB1 allelic epitopes that associate with autoimmune disease risk or protection activate reciprocal macrophage polarization.

Project description:Associations between particular human leukocyte antigen (HLA) alleles and susceptibility to-or protection from-autoimmune diseases have been long observed. Allele-specific antigen presentation (AP) has been widely proposed as a culprit, but it is unclear whether HLA molecules might also have non-AP, disease-modulating effects. Here we demonstrate differential macrophage activation by HLA-DRB1 alleles known to associate with autoimmune disease risk or protection with resultant polarization of pro-inflammatory ("M1") versus anti-inflammatory ("M2") macrophages, respectively. RNA-sequencing analyses of in vitro-polarized macrophages in the presence of AP-incompetent short synthetic peptides corresponding to the third allelic hypervariable regions coded by those two HLA-DRB1 alleles showed reciprocal activation of pro- versus anti-inflammatory transcriptomes, with implication of corresponding gene ontologies and upstream regulators. These results identify a previously unrecognized mechanism of differential immune modulation by short HLA-DRB1-coded allelic epitopes independent of AP, and could shed new light on the mechanistic basis of HLA-disease association.

Effects of HLA DRB1*15:01 interactions with ⍺-syn32-46 on gene expression in the ileum

Project description:HLA DRB1*15:01 is overrepresentated in Parkinson's disease patients and binds with high affinity to the ⍺-synuclein peptide, 32-46. Immunization of humanized mice expressing HLA DRB1*15:01 with ⍺-syn32-46 induces enteric phenotypes similar to those of prodromal Parkinson's disease. We collected the ileum from HLA mice immunized with either Complete Freund's Adjuvant (CFA) with ⍺-syn32-46 or CFA alone, and sequenced the tissue with bulk RNA sequencing at 21 days post immunization to determine changes in gene expression.

Effects of HLA DRB1*15:01 interactions with ⍺-syn32-46 on gene expression in intestinal immune cells in mice

Project description:HLA DRB1*15:01 is overrepresentated in Parkinson's disease patients and binds with high affinity to the ⍺-synuclein peptide, 32-46. Immunization of humanized mice expressing HLA DRB1*15:01 with ⍺-syn32-46 induces enteric phenotypes similar to those of prodromal Parkinson's disease. We collected the small intestines from HLA mice immunized with either Complete Freund's Adjuvant (CFA) with ⍺-syn32-46 or CFA alone, sorted the CD45+ immune cells, then performed single-cell RNA sequencing to evaluate gene expression at single cell resolution.
