Natural compounds derived from quinoline and isoquinoline have gained significant attention due to their remarkable biological properties, encompassing antibacterial, anticancer and anti-inflammatory activities. Meanwhile, pyrazoles, a prominent class of heterocyclic compounds, exhibit a wide range of biological and pharmaceutical properties.
CD122 signaling plays a key role in the function of CD4, CD8 T cells and natural killer (NK) cells, as well as in the development and survival of tissue-resident memory T cells (TRMs).
Multiple sclerosis (MS) is and remains “a problem in the immune system” Stephen Sawcer told BioWorld. As in other autoimmune diseases, a faulty immune system attacks otherwise healthy tissues that it should be leaving alone. In the case of MS, the tissue in question is oligodendrocytes. And a study published online in Nature on June 28, 2023, suggests that while MS’ beginnings are autoimmune, the path it takes in an individual patient is determined in part by how well the brain can cope with the autoimmune attack.
The NLRP3 inflammasome is a multiprotein complex that plays a pivotal role in regulating the innate immune system and inflammatory signaling. Upon activation by pathogen-associated molecular patterns (PAMPs), NLRP3 oligomerizes and activates caspase-1 which initiates the processing and release of pro-inflammatory cytokines IL-1β and IL-1 that are overproduced in many inflammatory disease conditions.
At the recent EAACI meeting, researchers presented preclinical data for the inflammasome inhibitor OLT-1177 (dapansutrile), which is being evaluated by Olatec Therapeutics LLC for the treatment of inflammatory diseases.
Research at Seoul National University has led to the identification of thiourea compounds acting as nuclear receptor RORα (RORA) agonists reported to be useful for the treatment of inflammation and metabolic diseases.
Researchers have ameliorated both monogenic and complex inflammation-driven diseases through transplantation of hematopoietic stem cells with an inserted IL-1 receptor antagonist (IL-1RA) gene. The team showed that in animal models the transplanted cells worked better than monoclonal antibodies to reduce symptoms in systemic autoinflammatory diseases (SAIDs), a group of childhood-onset, lifelong diseases that vary in severity depending on the underlying mutation, but can be life-threatening.
Glucocorticoids are very effective immunosuppressive and anti-inflammatory drugs that cause dose-limiting toxicities in brain, liver and bone preventing their use mainly in chronic disorders. Researchers from Immunext Inc. recently reported results from the therapeutic evaluation of the nontoxic glucocorticoid INX-200 with anti-inflammatory efficacy in a once-per-month injection.
