Single-cell transcriptomics of peripheral blood reveals a novel B-cell subset in renal allograft recipients with accommodation
Ontology highlight
ABSTRACT: Kidney transplantation is a preeminent treatment for end-stage renal disease . The application of immunosuppressants is needed for kidney recipients to avoid allograft rejection but increase the risk of infection, and balance between rejection and infection is an important in clinical to reach the immune accommodation. Here, we use single-cell RNA sequencing to fully assess the immune status of peripheral mononuclear cells in kidney recipients. and compared the differences between kidney recipients and healthy people to describe the characteristics of the immune accommodation of kidney recipients. We found a novel B cell subset (CD19+IGKC+IGLC3lowTCL1A-CD127+) of renal transplant recipients with accommodation was significantly lower than that of healthy people and verified by flow cytometry. which may have potential regulatory potential. Furthermore, we found that IL32 may increase the expression of CD19+IGKC+IGLC3lowTCL1A-CD127+ Bcells. In summary, we found that the CD19+IGKC+IGLC3lowTCL1A-CD127+B subgroup with immunomodulatory potential is inhibited in kidney recipients with accommodation state, and IL-32 has therapeutic potential for this.
