[CD4.sup.+] T cells play a critical role in the pathogenesis of viral diseases, which are activated by the internal metabolic pathways encountering with viral antigens. Glutaminolysis converts glutamine into tricarboxylic acid (TCA) circulating metabolites by [alpha]-ketoglutaric acid, which is essential for the proliferation and differentiation of [CD4.sup.+] T cells and plays a central role in providing the energy and structural components needed for viral replication after the virus hijacks the host cell. Changes in glutaminolysis in [CD4.sup.+] T cells are accompanied by changes in the viral status of the host cell due to competition for glutamine between immune cells and host cells. More recently, attempts have been made to treat tumours, autoimmune diseases, and viral diseases by altering the breakdown of glutamine in T cells. In this review, we will discuss the current knowledge of glutaminolysis in the [CD4.sup.+] T cell subsets from viral diseases, not only increasing our understanding of immunometabolism but also providing a new perspective for therapeutic target in viral diseases. Keywords: [CD4.sup.+] T cells, viral diseases, glutamine, glutaminolysis, immune response
Introduction In viral diseases, metabolic reprogramming of the host's cell occurs in response to viral infection. First, the virus hijacks the metabolic pathways and protein synthesis mechanisms of host cells [...]
