How does the addition of carboxylmethyl chitosan affect the morphology and properties of the resulting calcium phosphate?
5 answers
The addition of carboxymethyl chitosan (CMC) to calcium phosphate (CaP) composites significantly influences their morphology and properties. Incorporating CMC into CaP scaffolds results in the formation of a composite scaffold (CSHA) with enhanced odontogenic differentiation potential on human dental pulp stem cells (hDPSCs). The CSHA scaffold exhibits a porous microstructure with a Ca/P molar ratio of 1.67, promoting bioactivity and consistent pH maintenance during in-vitro studies. Moreover, CSHA shows increased alkaline phosphatase (ALP) and mineralization activity compared to Biodentine, indicating superior biomineralization abilities. This suggests that the addition of CMC to CaP enhances the scaffold's bioactivity, odontogenic differentiation, and mineralization potential, making it a promising candidate for pulp capping applications.

What is the function of ninj1?
4 answers
Ninjurin1 (NINJ1) is a multifaceted membrane protein that plays a crucial role in various biological processes, including cell adhesion, axonal growth, plasma membrane rupture (PMR), and the regulation of inflammatory responses. NINJ1 is upregulated by nerve injury to increase cell adhesion and promote axonal growth in neurons, highlighting its importance in nerve regeneration. Beyond its role in nerve injury response, NINJ1 has been identified as an active executioner of PMR, a process previously thought to be a passive event in lytic cell death. This protein mediates PMR by forming ring-like structures that rupture liposome membranes, leading to their dissolution, a mechanism distinct from its close paralog NINJ2, which lacks this capability. In the context of disease, NINJ1's expression and function have been linked to severe acute pancreatitis (SAP), where it mediates PMR in acinar cells, suggesting a potential target for treatment. Additionally, NINJ1 plays a critical role in disseminated intravascular coagulation (DIC) and sepsis by regulating platelet function and preventing thrombosis. Its involvement extends to liver ischemia-reperfusion injury, where it regulates sterile inflammation and neutrophil infiltration, further underscoring its significance in inflammatory responses. NINJ1's role in gout pathogenesis has been demonstrated through its upregulation during gout flares, where it induces PMR and correlates with disease progression. Moreover, in liver diseases and lung cancer, NINJ1 has been implicated in promoting inflammation and tumor progression, respectively, by mediating cell death and enhancing the survival of cancer stem-like cells in non-small cell lung cancer (NSCLC). Collectively, these studies reveal NINJ1 as a pivotal protein involved in cell death, inflammation, and disease progression, making it a potential therapeutic target across various conditions.
