Lymphocyte expansion molecule

Lymphocyte expansion molecule (LEXM) is a protein discovered in 2015, found to be involved in immune responses (in mice) to some cancers and viruses.^[1][2] The protein was initially found to be responsible for an increased production of T cells in mice. The original paper has since been retracted upon recommendation of Imperial College's investigators due to concerns about duplication of data.^[3] The protein may be relevant to humans and could be a target for drug discovery.^[4][5]

Scientists at Imperial College are developing a gene therapy based on this protein.^[1]
