Impact of Hells loss-of-function on DNA methylation in B cells during humoral immune responses: kinetic comparison of Mb1-Hells knockout and control mice by enzymatic-methyl sequencing. Impact of Hells loss-of-function on DNA methylation in B cells during humoral immune responses: kinetic comparison of Mb1-Hells knockout and control mice by enzymatic-methyl sequencing

We are interested in deciphering the mechanism by which DNA methylation in late B cell differentiation affects humoral immune response. We were using enzymatic-methyl sequencing (EM-seq) and chose to study a very rare immunodeficiency called ICF type 4, where a point mutation in a gene encoding the protein HELLS causes a lack of both circulating antibodies and memory B cells in human. HELLS is a chromatin remodeler, that allows for DNA methylation to occur.
