ADSL and hematopoietic and lymphoid system neoplasm: In the present study, we provided evidence that AMPs are induced as a consequence of activation of the innate immune pathways in response to haematopoietic tumours in Drosophila. Our observations showed that three different AMPs enhanced apoptosis in the tumours through two different routes, either with the aid of circulating haemocytes or through direct binding to the tumour cells.
