Abstract The objective of this research study is to profile anti-viral and pro-inflammatory cytokines, major histocompatibility complex (MHC) class I & II molecules cell death markers in clinical cases sepsis. Research design included three patient cohorts namely, COVID-19 with sepsis (C19wSepsis, N=17), no (C19NoSepsis, N=17) alone (N=24). Healthy subjects served as controls (N=16). Serum ...

PURPOSE Interleukin-(IL)1beta expression is increased in the retina during a variety of diseases involving the death of retinal neurons and contributes to neurodegenerative processes through an unknown mechanism. This study was conducted to examine the effects of IL-1beta on the metabolism and viability of RGC-5 and R28 retinal neuronal cells. METHODS Cellular reductive capacity was evaluated...

Chronic inflammation rather than invasion is characteristic of some forms of superficial candidiasis such as denture stomatitis. We hypothesized that Candida albicans may play a critical role in the pathogenesis of inflammatory lesions observed in chronic candidiasis by activating the proinflammatory cytokine interleukin-1beta (IL-1beta) from epithelial stores of the precursor. The aim of this ...

We have previously demonstrated that full-length interleukin (IL)-1beta can induce and stimulate lung fluid absorption in near-term guinea pig fetuses via stimulation of fetal cortisol synthesis and release. To develop a potentially clinically useful drug, we tested the hypothesis that maternal administration of a noninflammatory IL-1beta-fragment (IL-1beta(Fr)) induced cortisol synthesis and s...

PURPOSE Diabetic retinopathy is shown to share many similarities with chronic inflammatory disease, and in diabetes, accelerated apoptosis of retinal capillary cells is evident before histopathology can be seen. The purpose of this study was to examine the effect of interleukin (IL)-1beta on capillary cell apoptosis in rat retina and to determine the effect of antioxidants on diabetes-induced c...

We investigated the role of interleukin-1beta (IL-1beta) and prostaglandins (PG) in the alpha(1)-adrenergic agonist, phenylephrine-induced hypothalamic-pituitary-adrenal axis (HPA) responses under basal and social stress conditions. Male Wistar rats, either control or exposed to crowding stress for 7 days prior to treatment, were used in these experiments. All compounds were injected i.p. Cyclo...

Although interleukin-1beta (IL-1beta) administration produces nonuniform changes in the level of sympathetic nerve discharge (SND), the effect of IL-1beta on the frequency-domain relationships between discharges in different sympathetic nerves is not known. Autospectral and coherence analyses were used to determine the effect of IL-1beta and mild hypothermia (60 min after IL-1beta, colonic temp...

Interleukin-1beta (IL-1beta) is a potent pro-inflammatory cytokine that is primarily produced by microglia in the brain. IL-1beta inhibits N-methyl-d-aspartate (NMDA)-induced outward currents (I(NMDA-OUT)) through IL-1 type I receptor (IL-1RI) in hippocampal CA1 neurons (Zhang, R., Yamada, J., Hayashi, Y., Wu, Z, Koyama, S., Nakanishi, H., 2008. Inhibition of NMDA-induced outward currents by in...

Transforming growth factor beta1 (TGFbeta1) acts as an inhibitor of the actions of interleukin-1beta (IL-1beta) in various organ systems. In order better to understand the inter|P-actions between these polypeptides in the ovary, we evaluated the effect of TGFbeta1 co-treatment on various IL-1beta-mediated actions in cultures of whole ovarian dispersates. Treatment with IL-1beta enhanced media a...

It has been suggested that proinflammatory cytokines communicate to the brain via a neural pathway involving activation of vagal afferents by interleukin-1beta (IL-1beta), in addition to blood-borne routes. In support, subdiaphragmatic vagotomy blocks IL-1beta-induced, brain-mediated responses such as fever. However, vagotomy has also been reported to be ineffective. Neural signaling would be e...
