title: Retinoids and in vivo immunity to transplantable tumours: a terra relatively incognita.
abstract: Miroslav Malkovský and Peter Medawar discuss here the role of retinoids in anti-tumour immunity in vivo with the intention of provoking a reassessment of the current status and potential of this topic. Their selection of results discussed is influenced by the belief that they may form a basis for a renaissance in the study of the biological functions of vitamin A.
