The Fear Lab is currently investigating molecular mechanisms regulating Human B cell germinal centre activities. In particular, identifying transcription factors, chromatin remodelling enzymes and microRNAs that regulate B cell fate and the regulation of class switching to IgE and behaviour of IgE+ B cells.

Transcriptomic profiling of IgE producing B cells

We have previously shown that the isotype of antibody that B cells produce profound effects on their function, survival, longevity and differentiation potential. Critically, naïve B cells undergo Immunoglobulin class switching less readily than memory or germinal centre B cells and switchless frequently to IgE than to IgG6. But, IgE+ B cells show more rapid differentiation to plasma cells than IgG+ cells whilst retaining their proliferative capacity. We are now employing population level and single-cell transcriptomic profiling of different Naïve, IgE+ and IgG+ B cell populations to understand the mechanisms that regulate their different behaviour.

    Identification of transcription factors and miRNAs that regulate B cell activities

    We have identified many transcription factors and miRNAs that are differentially expressed at specific stages of B cell activation and differentiation. We are now using siRNA and CRISPR/Cas9 technologies to manipulate the expression of these factors to elucidate their role in B cell regulation.
