Plague, caused by , poses a public health threat not only due to sporadic outbreaks across the globe but also due to its potential as a biothreat agent. Ironically, among the seven deadliest pandemics in global history, three were caused by . Pneumonic plague, the more contagious and severe form of the disease, is difficult to contain, requiring either prophylactic antibiotic treatment or vaccination.

Dysregulated inflammation and oxidative stress are strongly implicated in the pathogenesis of inflammatory bowel disease. We have developed a novel therapeutic that targets inflammation and oxidative stress. It is comprised of microRNA-146a (miR146a)-loaded cerium oxide nanoparticles (CNPs) (CNP-miR146a).

Primary Sjögren's syndrome (pSS) is an autoimmune disease characterized by the infiltration of lymphocytes on salivary and lacrimal glands, resulting in their dysfunction. Patients suffering from severe pSS have an increased risk of developing multi-organ dysfunction syndrome due to the development of systemic inflammatory response, which results in immune cell-driven injury of the lungs, kidneys, liver, and brain. Therapeutic agents that are used for the treatment of severe pSS encounter various limitations and challenges that can impact their effectiveness.

Blocking the Sphingosine-1-Phosphate Receptor 2 (S1P) Reduces the Severity of Collagen-Induced Arthritis in DBA-1J Mice.

The amount of sphingosine 1-phosphate (S1P) found in the synovial tissue of individuals with rheumatoid arthritis is five times greater than that in those with osteoarthritis. Our study aims to determine whether inhibiting S1P can mitigate collagen-induced rheumatoid arthritis (CIA) by using an S1P antagonist, JTE-013, alongside DBA-1J wild-type (WT) and knock-out (KO) mice. CIA causes increases in arthritis scores, foot swelling, synovial hyperplasia, pannus formation, proteoglycan depletion, cartilage damage, and bone erosion, but these effects are markedly reduced when JTE-013 is administered to WT mice.

Sub-Saharan Africa (SSA) bears a disproportionate and overlapping burden of soil-transmitted helminths (STHs) and sexually transmitted viral infections. An estimated 232 million pre-school and school-aged children in SSA are vulnerable to STH infections. Together with this, SSA has a high prevalence of herpes simplex virus type II (HSV-2), the primary cause of genital herpes.
