LGALS3BP and myasthenia gravis: In TME-infiltrating MG, besides the presence of previously described clusters MG1-2, we found a MG7 cluster characterized by increased expression of genes encoding the components of MHC class I (B2m, H2-D1, and H2-K1) and MHC class II (H2-Oa and H2-DMa), Bst2 and Lgals3bp, upregulation of which has been reported in disease-associated microglia36,37, and Ccl12 encoding a cytokine critical for CCR2+ Mo recruitment38.
