NIAID herpesvirus study in mice leads to discovery of potential broad-spectrum antiviral
NIAID scientists studying herpes simplex virus infection have unexpectedly found that inhibiting a cellular enzyme complex, EZH2/1, suppresses viral infection. The researchers then demonstrated that EZH2/1 inhibitors also enhanced the cellular antiviral response in cultured cells and mice. They then showed that EZH2/1 inhibitors suppressed HSV infection, spread, and reactivation in mice and, in cell culture, suppressed human cytomegalovirus, adenovirus, and Zika virus infections. They suggest that EZH2/1 inhibitors have considerable potential as broad-spectrum antivirals. (2017-08-15)

NIH scientists show how tularemia bacteria trick cells to cause disease
Francisella tularensis is the bacterium that causes tularemia, a life-threatening disease spread to humans via contact with an infected animal or through mosquito, tick or deer fly bites. NIAID scientists have unraveled the process by which the bacteria cause disease, finding that F. tularensis tricks host cell mitochondria, which produce energy for the cell, in two different phases of infection. These basic science findings could play a role in developing effective treatment strategies. (2018-05-30)

Special antibodies could lead to HIV vaccine
Around one percent of people infected with HIV produce antibodies that block most strains of the virus. These broadly acting antibodies provide the key to developing an effective vaccine against HIV.

NIAID scientists link cases of unexplained anaphylaxis to red meat allergy
While rare, some people experience recurrent episodes of anaphylaxis -- a life-threatening allergic reaction -- for which the triggers are never identified. Recently, researchers at NIAID found that some patients' seemingly inexplicable anaphylaxis was actually caused by an uncommon allergy to a molecule found naturally in red meat. They note that the allergy, which is linked to a history of a specific type of tick bite, may be difficult for patients and health care teams to identify. (2017-11-28)

Tuberculosis: Pharmacists develop new substance to counteract antimicrobial resistance

Lines blurring between human herpes simplex viruses
The herpes simplex virus (HSV-1) that commonly infects the mouth, is continuing to mix with the genital herpes virus (HSV-2) to create new, different recombinant versions. Genital co-infection with both viruses could create opportunities for the viruses to recombine. This ability of the viruses to recombine poses problems for vaccine development, due to the risk of a live vaccine for genital herpes mixing with HSV-1 to form an infectious recombinant. (2019-04-30)

NIAID scientists develop 'mini-brain' model of human prion disease
Scientists have used human skin cells to create what they believe is the first cerebral organoid system, or 'mini-brain,' for studying sporadic Creutzfeldt-Jakob disease (CJD). CJD is a fatal neurodegenerative brain disease of humans believed to be caused by infectious prion protein. The researchers, from NIH's National Institute of Allergy and Infectious Diseases, hope the human organoid model will enable them to evaluate potential CJD therapeutics and provide greater detail about human prion disease subtypes.
