TCPG (T Cell Perturbation Genomics database) is a database providing comprehensive resources and functional analysis for searching potential T cell gene. It collected the best CRISPR genome wide screen dataset for priotizing the overall gene function by aggregating result from multi-studies. It also include gene iinformation in T-ALL cancer prognosis. It is the first database for systematically investigating T cell gene functions and we aim to provide useful data and clues for T cell based therapy related clinical research.
