Many adult stem cells, namely mesenchymal stem cells (MSCs) and neural stem cells (NSCs), have intrinsic tumour-tropic properties, which makes them a novel targeted cellular delivery vehicle for anti-cancer agents. Major engineered stem cells for delivery of anti-cancer agents Stem cells as a potential targetĬharacteristics such as a high proliferative capacity, low immunogenic reactivity and differentiating capabilities mark stem cells out as potential therapeutics – along with challenges such as unclear expression profiles in vivo and their potential immune-reactivity. Upcoming advancements in immunotherapy include improvements in translational research, patient stratification, target validation and the development of predictive biomarkers. These cells are then administered to the patient after being generated in greater numbers to initiate a massive antitumour immune response. These are analysed based on the receptors’ specificity or to determine which receptors are more specific to the tumour. Adoptive T-cell therapy or adoptive cell transfer therapy: this is designed to enrich tumour infiltration lymphocytes by multiplying T-cells removed directly from the patient’s tumour microenvironment.This is directed against the cancer cells, which silence the body’s T-cell functioning by taking advantage of the immune system’s natural checkpoints designed to maintain equilibrium and prevent autoimmunity Checkpoint inhibitors (CTLA4, PD1 and PDL1): these release the breaks on the body’s immune system and induce T-cells to actively combat tumour growth.They are designed to target specific antigens found on cancer cells Tumour targeted monoclonal antibodies (mAbs): these block the growth signal of tumour cells or induce apoptosis.Immune modulators: these boost the patient’s entire immune system not only those immune cells active within the tumour microenvironment.Four common approaches to immunotherapy include the following: This therapy makes use of the body’s own internal defenses to combat or check cancer growth and metastasis. Immunotherapy represents an entirely new approach to cancer treatment targeting the immune system rather than the tumour itself. These undifferentiated stem cells are a powerful tool in clinical research to help unravel the mystery of cancer progression and development of stem-cell technologies is the ultimate goal. Immunotherapy has changed our approach to cancer treatment by targeting the immune system rather than the tumour itself this has been the consequence of better understanding the precise cellular interactions between cancer and the immune system. This combination of immunotherapy and stem-cell technology has the potential to revolutionise cancer treatment regimes. In recent years, scientists have developed many therapeutic molecules – such as bifunctional multi-targeting antibodies, fusion proteins and oncolytic viruses – and different types of stem cells are being modified to facilitate their efficient delivery to tumours, illustrating the great potential of engineered therapeutic stem cells. Ageing cells have proven to be a major challenge in generating these cancer-fighting cells but induced pluripotent stem cell (iPSC) technology, which allows adult cells to be reprogrammed in the laboratory and returned to a stem cell state, is helping to overcome this. This represents a milestone for immunotherapy developing more vigorous anti-cancer cells and using a similar approach to produce large quantities of cancer-fighting cells from patients’ own blood cells. THE AMALGAMATION of stem-cell technology with an immunotherapy approach has produced a new method that rejuvenates cancer-fighting immune cells and strengthens the ability of ageing cells to replicate in the body and mediate tumour regression.
