Engineers with the University of Cincinnati have created a tiny portable lab that plugs into your phone, connecting it automatically to a doctor’s office through a custom app UC developed. The lab the size of a credit card can diagnose infectious diseases such as coronavirus, malaria, HIV or Lyme disease or countless other health conditions like depression and anxiety.

The patient simply puts a single-use plastic lab chip into his or her mouth then plugs that into a slot in the box to test the saliva.

New antiviral materials m lade from sugar have been developed to destroy viruses on contact and may help in the fight against viral outbreaks.

This new development from a collaborative team of international scientists shows promise for the treatment of herpes simplex (cold sore virus), respiratory syncytial virus, hepatitis C, HIV, and Zika virus to name a few. The team have demonstrated success treating a range of viruses in the lab – including respiratory infections to genital herpes.

The research is a result of a collaboration between scientists from The University of Manchester, the University of Geneva (UNIGE) and the EPFL in Lausanne, Switzerland...

The IgM antibody has multiple arms to catch the virus, making it more efficient in clumping up the virus and keeping it from passing through the mucosal barrier and entering the rest of the body.

A group of scientists at Texas Biomedical Research Institute have zeroed in on a new defense against HIV-1, the virus that causes AIDS. Led by Ruth Ruprecht, M.D., Ph.D., the team used an animal model to show for the first time that Immunoglobulin M (IgM) was effective in preventing infection after mucosal AIDS virus exposure. Worldwide, an estimated 90% of new cases of HIV-1 are caused through exposure in the mucosal cavities like the inside lining of the rectum or vagina. “IgM is sort of the forgotten antibody,” Dr...

TFC cells express CXCR5 to localize to B cell follicles.

New research has taken us a step closer to finding a cure for HIV, as well as other infections including the glandular fever virus, which is associated with the development of lymphoma. Some infections, such as HIV, cannot be cured with antiviral therapy because the virus effectively hides from the immune system.

An international team of scientists have discovered that killer T cells can find these “hidden” infected cells in tissue and destroy them. “We’ve shown for the first time that there are specialised killer T cells that can migrate into a part of the lymphoid tissue and control hidden infection,” Dr Yu said.

Although treatments for HIV with antiretroviral drugs are highly effective, treatment is lifelong and there is no cure...
