Notch signalling is an evolutionarily conserved multifaceted pathway that controls diverse cellular processes. Its role in regulating development and tissue homeostasis is well established. Aberrant activation of the Notch pathway has been implicated in the initiation and progression of many types of cancers. However, although in some cancers Notch signalling acts as a tumour-promoter, in others it is reported to suppress tumour growth and progression. Accumulating evidence suggests the involvement of both the innate and adaptive immune system in the development of various tumours. Currently, extensive studies on investigating the effects of Notch signalling in tumour immune surveillance are being carried out. Interestingly, recent literature shows how the changing expression of Notch genes in different T cell subsets like CD4 and CD8 helps in controlling anti-tumour immune responses. In this review, we discuss in depth the roles of Notch signalling molecules and different immune cells in the context of the tumour microenvironment. We also outline how current knowledge can be exploited to develop novel therapies in order to control the propagation of cancer stem cells.
