High concentrations of IL-2 and IL-7 in serum are characteristic of severe COVID-19 cases.6, 9 However, IL-2 and IL-7 might amplify ILC2 survival and differentiation induced by IL-33,33 expand γδ T cells, which produce IL-17 through the signal transducer and activator of transcription (STAT)3,34 and enhance IL-33-induced pathologic expansion of T cells expressing GM-CSF through STAT5.35, 36 Patients infected with SARS-CoV-2 show an increase in circulating CD4+ γδ T cells that overexpress the IL-2 receptor CD25 but not PD-1, suggesting that these cells are not exhausted, but are specifically activated in response to IL-2.22"}
