Dear Colleagues  I read with great interest your paper in Nature Medicine, and would like to congratulate you for this important contribution against Covid. As member (and fan) of the HCA, I would like to suggest you to add to the *COVID-19 Cell Atlas *website our cell-sorted human gamma delta T lymphocytes scRNASeq dataset (n=8k cells), freely available at NCBI GEO data sets as *GSE128223*. The (cell, gene) matrix is included and  readily downloadable from this site, or else we can directly provide you with if you prefer. Here are 2 important reasons for adding it: 1-It is the only scRNASeq (10xgenomics Chem. 3' V2) resource available for these human T cells, which were TCR purified by state of the art techniques. 2-  gamma delta T lymphocytes are abundantly resident in all epithelia and mucosal human tissues and mediate innate immunity resposnes. If interested, read our paper by Pizzolato, G., et al.  :  Single-cell RNA sequencing unveils the shared and the distinct cytotoxic hallmarks of human TCRVdelta1 and TCRVdelta2 gammadelta T lymphocytes. PNAS (2019): 116, 11906-11915.  Best regards, and bravo anyway -- Jean Jacques Fournié, PhD Team noLymits Cancer Research Center of Toulouse CRCT-UMR1037 Inserm-Université Toulouse 3-ERL5294 CNRS Oncopole de Toulouse, 2 Avenue Hubert Curien, CS 53717 31037 TOULOUSE CEDEX 1 - FRANCE office: +335 8274 1590 mobile: +336 1990 0602 website: https://urldefense.proofpoint.com/v2/url?u=http-3A__www.crct-2Dinserm.fr&am…
