VCAM1 and axial length measurement: In the BM of AL patients, we found a cluster (C3) of CD8+GZMK+TRM cells with increased expression of EOMES TF target genes, high expression of genes associated with non‐lymphoid tissue residence (CD69, CXCR6, RGS1, VCAM1 and its receptor ITGAD) and low expression of TEMRA‐related genes.
