Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Nanoparticle-Mediated Enhanced Delivery of an Anti-Inflammatory Drug in Microglia-Like Cells01:33

Nanoparticle-Mediated Enhanced Delivery of an Anti-Inflammatory Drug in Microglia-Like Cells

Take cultures of human monocyte-derived microglia-like cells.Introduce nanoparticles containing an anti-inflammatory drug into the experimental culture and the free drug into the control.The nanoparticles feature a hydrophilic shell and a hydrophobic core encapsulating the lipophilic drug.The cells endocytose the nanoparticles, which release the drug intracellularly, enhancing its delivery.The free drug enters by passive diffusion, a process constrained by the concentration gradient, which...

Bile Duct Ligation in Mice: Induction of Inflammatory Liver Injury and Fibrosis by Obstructive Cholestasis08:56

Bile Duct Ligation in Mice: Induction of Inflammatory Liver Injury and Fibrosis by Obstructive Cholestasis

Disruption of bile flow results in severe inflammatory cholestatic liver injury with a characteristic time-dependent sequence of morphological alterations. Here we present a protocol for the surgical ligation of the common bile duct in mice that allows to induce a strong fibrotic response after 21 to 28...
