Regulatory T (Treg) cells are involved in the antiviral immune response in patients with coronavirus disease 2019 (COVID-19); however, whether Treg cells are involved in the neutralizing antibody (nAb) response remains unclear. Here, we found that individuals who recovered from mild but not severe COVID-19 had significantly greater frequencies of Treg cells and lower frequencies of CXCR3+ circulating T follicular helper (cTfh) cells than healthy controls. Furthermore, the frequencies of Treg and CXCR3+ cTfh cells were negatively and positively correlated with the nAb responses, respectively, and Treg cells was inversely associated with CXCR3+ cTfh cells in individuals who recovered from mild COVID-19 but not in those with severe disease.

Data Sources: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health, Cochrane Controlled Register of Trials, and Physiotherapy Evidence Database were searched from inception to January 2022.
Study Selection: Independent reviewers selected randomized controlled trials that compared the effects of home-based exercise alone with no treatment or other conservative treatments in individuals with nonsurgical painful shoulder disorders.
