Harnessing HLA‐E‐restricted CD8 T lymphocytes for adoptive cell therapy of patients with severe COVID‐19

2020

SARS-CoV-2 is spreading worldwide, and is a pandemic virus that has infected almost 5 million individuals and causing 300.000 deaths, as of mid-May 2020. Because SARS-CoV-2 is a new virus in humans there are currently no vaccines, monoclonal antibodies (mAbs) or even effective drugs available. Human convalescent plasma transfusion is an option for either prophylactic or therapeutic treatment of COVID-19 patients, but its administration to patients who are affected by severe pulmonary disease is associated with increased risk of transfusion-related acute lung injury (TRALI).

Human CD8 T lymphocytes recognize Mycobacterium tuberculosis antigens presented by HLA-E during active tuberculosis and express type 2 cytokines

2015

CD8 T cells contribute to protective immunity against Mycobacterium tuberculosis. In humans, M. tuberculosis reactive CD8 T cells typically recognize peptides associated to classical MHC class Ia molecules, but little information is available on CD8 T cells recognizing M. tuberculosis Ags presented by nonclassical MHC class Ib molecules. We show here that CD8 T cells from tuberculosis (TB) patients recognize HLA-E-binding M. tuberculosis peptides in a CD3/TCR αβ mediated and CD8-dependent manner, and represent an additional type of effector cells playing a role in immune response to M. tuberculosis during active infection. HLA-E-restricted recognition of M. tuberculosis peptides is detectab…

HLA-E-Restricted CD8+ T Lymphocytes Efficiently Control Mycobacterium tuberculosis and HIV-1 Co-Infection

2020

We investigated the contribution of human leukocyte antigen A2 (HLA-A2) and HLA-E-restricted CD8+ T cells in patients with Mycobacterium tuberculosis and human immunodeficiency virus 1 (HIV-1) coinfection. HIV-1 downregulates HLA-A, -B, and -C molecules in infected cells, thus influencing recognition by HLA class I-restricted CD8+ T cells but not by HLA-E-restricted CD8+ T cells, owing to the inability of the virus to downmodulate their expression. Therefore, antigen-specific HLA-E-restricted CD8+ T cells could play a protective role in Mycobacterium tuberculosis and HIV-1 coinfection. HLA-E- and HLA-A2-restricted Mycobacterium tuberculosis-specific CD8+ T cells were tested in vitro for cyt…
