Arthritis & Rheumatology

Many people start to feel pain and stiffness in their bodies over time. Sometimes their hands or knees or shoulders get sore and are hard to move and may become swollen. These people may have arthritis. Arthritis may be caused by inflammation of the tissue lining the joints. Some signs of inflammation include redness, heat, pain, and swelling.

What is Arthritis?

There are over 100 disorders that typically affect joints, tendons, ligaments, bones, and muscles and are termed arthritis and rheumatic diseases. Some of these may also involve internal organs.

Yale study offers critical clues for future norovirus treatments

As the leading cause of viral gastroenteritis worldwide, norovirus is an all too familiar ailment. Its telltale digestive upset — not to mention its reputation for being notoriously contagious — has earned it the nicknames "winter vomiting bug" and "stomach flu."

New cell culture method allows targeted study of antibody regulation

For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance.

Spermidine supplement improves COVID 19 vaccine response in older adults

As we age, the immune system gradually declines and becomes less effective at responding to infections and vaccines.

New review highlights TREM-1 receptor as target for inflammatory diseases

A comprehensive review recently published in Current Molecular Pharmacology consolidates the growing evidence surrounding the Triggering Receptor Expressed on Myeloid Cells-1 (TREM-1) as a central amplifier of innate immune responses and a promising therapeutic target for a range of inflammatory diseases.

Strength training plus cardio cuts type 2 diabetes risk the most

A 20-year prospective cohort study of 143,715 US healthcare professionals found that long-term resistance training was associated with a substantially lower risk of type 2 diabetes. The lowest risk was seen among participants who combined regular resistance training with adequate aerobic activity and limited TV viewing.
