The immune system of patients infected by SARS-CoV-2 is severely impaired.
Detailed investigation of T cells and cytokine production in patients affected by
COVID-19 pneumonia are urgently required. Here we show that, compared with
healthy controls, COVID-19 patients' T cell compartment displays several
alterations involving naïve, central memory, effector memory and terminally
differentiated cells, as well as regulatory T cells and PD1(+)CD57(+) exhausted T
cells. Significant alterations exist also in several lineage-specifying
transcription factors and chemokine receptors. Terminally differentiated T cells
from patients proliferate less than those from healthy controls, whereas their
mitochondria functionality is similar in CD4(+) T cells from both groups.
Patients display significant increases of proinflammatory or anti-inflammatory
cytokines, including T helper type-1 and type-2 cytokines, chemokines and
galectins; their lymphocytes produce more tumor necrosis factor (TNF),
interferon-?, interleukin (IL)-2 and IL-17, with the last observation implying
that blocking IL-17 could provide a novel therapeutic strategy for COVID-19.
