Gum disease may lie at the root of some arthritis flareups

Medical Xpress

The findings, published in Science Translational Medicine, suggests that breaches in damaged gums allow bacteria in the mouth to seep into the bloodstream, activating an immune response that ultimately pivots to target the body's own proteins and causes arthritis flareups.

Valneva accelerates Lyme disease vaccine R&D project with Pfizer

pharmaphorum

This investigational multivalent protein subunit vaccine targets the outer surface protein A (OspA) of the bacterium Borrelia that causes the disease, an established mechanism of action for a Lyme disease vaccine. VLA15 has demonstrated a promising immune response and safety data in pre-clinical and clinical studies so far.

What Do We Really Know About Macrophage Programming?

XTalks

Macrophages are white blood cells that specialize in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In other words, when fighting bacteria, the macrophages are programmed to be pro-inflammatory. They found a protein called Rspondin3, which is released at high levels during inflammatory injury.

Scientists use mRNA to reprogramme the immune system

Drug Discovery World

Dr Kaustav Das Gupta and Professor Matt Sweet from UQ’s Institute for Molecular Bioscience discovered that a molecule derived from glucose in immune cells can both stop bacteria growing and dampen inflammatory responses. Coli bacteria from growing,” Dr Das Gupta said. “It

Leading innovators in coronavirus vaccine components

Pharmaceutical Technology

The key component in all vaccines is one or more active ingredients made from viruses or bacteria, also called antigens, which generates an immune response. The active component of the Pfizer-BioNTech vaccine tozinameran, contains the genetic code for the coronavirus spike protein, inside a lipid (fat) capsule.

Mutations leading to omicron variant did not enable virus to fully escape immune system

The Pharma Data

People who gained immunity – either through vaccination or exposure – against the original strain of SARS-CoV-2, the virus that causes COVID-19, also are likely to have some protection against the pathogen’s omicron variant. The samples were stored after the researchers measured the T cell response. population.
