Abstract
Background: Chronic Lymphocytic Leukaemia (CLL) is an indolent disorder, which mainly affects older adults. Since the advent of chemoimmunotherapy, great progress has been made in its treatment. However, some patients develop a more aggressive form of the disease and are included in the group of high-risk CLL patients with a dismal prognosis and a need for new therapies.
Objective: Maltotriose-modified poly(propylene imine) dendrimers were presented as potential agents in targeted therapy for CLL in the murine xenograft model. Methods: Tumour, brain and internal organs resected from NOD scid gamma mice were subjected to gross and histopathological evaluation. Results: The results of ex vivo tissue examination indicated that open-shell glycodendrimers prevented/inhibited the spread of CLL into the brain and internal organs and its transformation into a more aggressive form. Conclusion: The results of the study have a potentially important impact on the design of future personalized therapies as well as clinical trials.Keywords: Poly(propylene imine), dendrimer, tumour, chronic lymphocytic leukaemia, anticancer therapy, in vivo, ex vivo.
