Published: June 1993

Interleukin-1 (IL-1) is a polypeptide produced by a variety of cells and contributes to the general host response to inflammation. It displays a wide spectrum of inflammatory, metabolic, physiological, haematopoietic and immunological activities. Brain cells, including neurones, microglia, endothelial cells and astrocytes can all produce IL-1 beta in response to various physiological and pathological stimuli. In this report we show that peripherally administered endotoxin stimulates the appearance of immunoreactive IL-1 beta (IL-1 beta) in the rat hypothalamus as measured by an ultrasensitive, highly specific enzyme amplified immunometric assay for rat IL-1 beta.

Background: Epidemiological research suggests that altered levels of cytokine are associated with pathophysiology and the development of major depressive disorder (MDD). Based on earlier study, IL-1β rs16944 and rs1143627 polymorphisms may increase the risk of depression. Here, we aimed to evaluate the correlation between these polymorphisms and MDD susceptibility among the population in Bangladesh.

Osteoarthritis (OA) is increasingly recognized as a whole-organ disease predominantly affecting the elderly, characterized by typical alterations in subchondral bone and cartilage, along with recurrent synovial inflammation. Despite the availability of various therapeutics and medications, a complete resolution of OA remains elusive. In this study, novel functional hydrogels are developed by integrating natural bioactive molecules for OA treatment.

Background: Parkinson's disease (PD) is characterized by dopaminergic (DA) neuron loss, Lewy body build-up, and motor dysfunction. One of the primary pathogenic mechanisms of PD development is autophagy dysfunction and nitric oxide-mediated neurotoxicity.

Purpose: The current study focuses on autophagy and nitric oxide (NO) signaling roles in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-intoxicated PD mice and their protection by their modulators.

Introduction: CD38, a regulator of intracellular calcium signalling, is highly expressed in immune cells. Mice lacking CD38 are very susceptible to acute bacterial infections, implicating CD38 in innate immune responses. The effects of CD38 inhibition on NLRP3 inflammasome activation in human primary monocytes and monocyte-derived macrophages have not been investigated.

Purpose: The inflammatory response in animal models of chronic obstructive pulmonary disease (COPD) is activated by the NLR-family-pyrin-domain-containing-3 (NLRP3) inflammasome pathway, which is also known to play a role in obesity-related inflammation. The NLRP3/caspase-1/interleukin (IL)-1β pathway might be involved in the progression of COPD with increasing body mass index. To our knowledge, no previous studies have explored the role of NLRP3 inflammasome markers in linking COPD and obesity.
