                            This invention relates to methods for the expansion of T-lymphocytes with a memory-like phenotype in which the intracellular concentration of a memory induction compound, such as 2-hydroxyglutarate (2HG), is increased in order to facilitate the maintenance of a memory-like phenotype. This may be useful for example, in cellular immunotherapy. The memory induction compound may the formula (I) wherein: p is 0 or 1, and when p is 0, Y is —CH
