Challenges in the Therapeutic Exploitation of Chemokine Receptor-Mediated Internalization of Nanocarriers.

Chemokines are small proteins guiding cell migration with crucial role during immune responses. Their actions are mediated by 7-helix trans-membrane Gα protein-coupled receptors and ended by chemokine-receptor complex downregulation. Beyond its physiological role, ligand-induced receptor endocytosis can be exploited to vehiculate drugs and genetic materials within specific cells.

Efficiency of Chitosan Nanocarriers in Vaccinology for Mucosal Immunization.

The mucosal barrier constitutes a huge surface area, close to 40 m in humans, located mostly in the respiratory, gastrointestinal and urogenital tracts and ocular cavities. It plays a crucial role in tissue interactions with the microbiome, dietary antigens and other environmental materials. Effective vaccinations to achieve highly protective mucosal immunity are evolving strategies to counteract several serious diseases including tuberculosis, diphtheria, influenzae B, severe acute respiratory syndrome, Human Papilloma Virus infection and Acquired Immune Deficiency Syndrome.

Anti-inflammatory potential of platinum nanozymes: mechanisms and perspectives.

Inflammation is a complex process of the body in response to pathogen infections or dysregulated metabolism, involving the recruitment and activation of immune system components. Repeated dangerous stimuli or uncontrolled immune effector mechanisms can result in tissue injury. Reactive Oxygen Species (ROS) play key roles in physiological cell signaling as well as in the destruction of internalized pathogens.
