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 The original paper has since been retracted upon recommendation of Imperial College's investigators due to concerns about duplication of data.[3] The protein may be relevant to humans and could be a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]
