Therapeutical effect of human recombinant IL-1 beta on exposed CBA mice was shown. Single injection of IL-1 beta into mice exposed to LD70, LD80 and LD100 raised their 30-day survival by 60, 40 and 35%, respectively. Therapeutically effective doses of IL-1 beta were 100-200 micrograms/kg. Multiple injections of the preparation were ineffective.

Tissue-invasive Pathogens in Periodontitis Patients and Their Correlation with Pro-inflammatory Markers: An Analytical Case-control Study.

Aim: Tissue-invasive bacteria have been proposed to be a crucial factor in the etiopathogenesis of periodontitis, with the probable interaction of tissue-invasive bacteria with the innate immune response through inflammasomes, perpetuating periodontal attachment loss. This study aims to reveal the correlation between such tissue-invasive bacteria in upregulating inflammasomes and pro-inflammatory cytokines.
Materials And Methods: This study recruited a total of 10 patients with stage III/IV and grade C periodontitis based on the bone loss to age ratio.

Background: The BCG vaccine induces trained immunity, an epigenetic-mediated increase in innate immune responsiveness. Therefore, this clinical trial evaluated if BCG-induced trained immunity could decrease coronavirus disease 2019 (COVID-19)-related frequency or severity.
Methods: A double-blind, placebo-controlled clinical trial of healthcare workers randomized participants to vaccination with BCG TICE or placebo (saline).
Modelling neurodegeneration and inflammation in early diabetic retinopathy using 3D human retinal organoids.

Purpose: Diabetic retinopathy (DR) is a complication of diabetes and a primary cause of visual impairment amongst working-age individuals. DR is a degenerative condition in which hyperglycaemia results in morphological and functional changes in certain retinal cells. Existing treatments mainly address the advanced stages of the disease, which involve vascular defects or neovascularization.

Scopoleitin (SP), a bioactive compound from many edible plants and fruits, exerts a wide range of biological activities, however the role and mechanism of SP in acetaminophen (APAP)-induced hepatotoxicity remains unclear. In this study, we verified the protective effect of SP on APAP-induced liver injury (AILI) hepatotoxicity and explore the underlying molecular mechanisms. Here, we showed that SP alleviated AILI by reducing serum alanine transaminase (ALT) and aspartate aminotransferase (AST) levels, hepatic histopathological damage, inflammation, and liver cell apoptosis.

Purpose: Rose Bengal Photodynamic Therapy (RB-PDT) offers dual therapeutic benefits by enhancing corneal stiffness and providing antibacterial activity, presenting significant potential for patients with keratoconus complicated by keratitis. Our purpose was to assess the effect of rose bengal photodynamic therapy (RB-PDT) on the expression of pro-inflammatory cytokines and chemokines, as well as on extracellular matrix (ECM)-related molecules, in lipopolysaccharide (LPS)-induced inflammation of keratoconus human corneal fibroblasts (KC-HCFs). Additionally, the involvement of the mitogen-activated protein kinase (MAPK) and nuclear factor kappa B (NF-κB) signaling pathways which are downstream of the Toll-like receptor 4 (TLR4) pathway were examined.
