Research Interest

Metabolic remodelling is required for B cell activation and antibody production, while B cell dysfunction is frequently observed in patients with viral infections, such as HIV-1 and SARS-CoV-2. Moreover, viruses have developed numerous mechanisms to evade immunosurveillance by inducing metabolic rewiring and immune dysregulation. My study aims to investigate the key role of an isoform of PD-1, Δ42PD1, spike protein of SARS-CoV-2, and pro-inflammatory cytokines in regulating cellular and metabolic signalling, thus how they shape B cell fate and function.
