Malaria is caused by a tiny parasite that infects human livers and red blood cells, and which is transmitted from person to person by a female mosquito. NIAID-funded researchers investigated how the parasite takes nutrients to complete completes critical life stages inside a mosquito without harming the mosquito's ability to lay eggs.

The common cold is one of the most frequent triggers of asthma attacks. Yet even among children with severe asthma, most colds do not lead to asthma attacks. In a new NIAID-funded study, researchers sought to answer a long-standing question: what differentiates a cold that leads to an asthma attack from a cold that is just a cold?

Somewhere in the deep past, bacteria from the deep sea made their way into mammalian guts. Now, with new genetic sequencing technology, scientists are uncovering these organisms' ancient paths. As part of NIH’s Demystifying Lecture, Dr. Sievert, an Associate Scientist in the Biology Department of the Woods Hole Oceanographic Institution, and Dr. John Dekker, Chief of the Bacterial Pathogenesis and Antimicrobial Resistance Unit in NIAID’s Laboratory of Clinical Immunology and Microbiology, discussed how pathogens have evolved from microbes living in some of the world’s most inhospitable environments, and how the latest science is helping us track and fight them.

See new infographics from the Centers of Excellences for Influenza Research and Surveillance (CEIRS) network. NIAID established the CEIRS network in 2007 to continue and expand the fight against emerging and developing strains of flu. CEIRS now helps provide information and public health tools to control the threats of both epidemic and pandemic influenza.

In their final conversation from CROI 2019, Dr. Carl Dieffenbach and Anne Rancourt of NIAID discussed research presented on a new formulation of pre-exposure prophylaxis. They also described findings that advance our understanding of the effects of inflammation associated with HIV infection. Finally, they fielded a viewer’s question about HIV treatment as prevention and looked ahead to HIV research findings anticipated later this year.

Even when HIV is well-controlled with antiretroviral therapy, the virus can cause persistent immune activation that contributes to an increased risk of complications such as heart disease and certain cancers. New NIAID-supported research presented today at CROI 2019 in Seattle sheds light on the relationship between immune activation and weight gain.

As the first full day of presentations at the 2019 Conference on Retroviruses and Opportunistic Infections began to wrap up, HIV.gov spoke with NIAID's Dr. Carl Dieffenbach about some of the new HIV research highlights presented, including the case of a patient reported to be possibly cured of HIV infection. They also discussed the promising findings from a large study evaluating a “universal test and treat” strategy, as well as other results showing improved viral suppression and retention in care when point-of-care viral load testing is offered.

Rarely, people living with HIV are unable to maintain an undetectable viral load despite strict adherence to antiretroviral therapy (ART). NIAID-funded research suggests that this sometimes can occur when a single cell from the HIV reservoir—the population of long-lived HIV-infected cells that ART cannot eradicate—multiplies to create many identical cells that produce enough virus to be detected by standard viral load tests.

HIV.gov kicked off coverage of the 2019 Conference on Retroviruses and Opportunistic Infections (CROI) with an interview with NIAID's Dr. Carl Dieffenbach just hours before the conference opened in Seattle. Dr. Dieffenbach spoke with his colleague Anne Rancourt about some of the current issues in the field of HIV research as well as what he is looking forward to learning more about at this year’s conference of HIV researchers from around the globe.

NIAID Director Anthony S. Fauci, M.D., addressed the 2019 Conference on Retroviruses and Opportunistic Infections (CROI) last night about Ending the HIV Epidemic: A Plan for America and the role HIV research will play in it. HIV.gov spoke with Dr. Fauci ahead of his remarks at the opening plenary session of the conference.

Tickborne diseases are a growing problem in the United States. In response to recommendations from the Tick-borne Disease Working Group, the NIH is developing a strategic plan to advance tickborne disease research and development, and is seeking comments and suggestions from stakeholders throughout the scientific research, advocacy, and clinical practice communities, and the general public.
With Antibody-Drug Combination, NIAID Scientists Improve Outcomes of Bone Marrow Transplants in Mice
February 26, 2019
Bone marrow transplants can be necessary for treating cancer and many other illnesses, but the process can be grueling. By using an antibody-drug combination to kill existing bone marrow stem cells, NIAID scientists were able to drastically improve bone marrow and skin transplant outcomes in mice.

NIAID has helped colleagues at Houston Methodist Hospital establish a “layered” big-data approach to analyze microbial genetic changes that can make some bacteria extremely dangerous to people.

People with food allergy need to remain watchful on Valentine’s Day, but they certainly shouldn’t be left out of the sweet celebrations! Carefully reading food labels on candies and other treats can help ensure a safe day for everyone.

Researchers have identified immunologic factors that predispose certain children to recurrent tonsil infections. While nearly everyone is exposed to strep bacteria during childhood, only some children develop recurrent tonsillitis. New findings uncover immune responses linked to recurrent tonsillitis and suggest a potential strategy for development of a vaccine to prevent strep infections.

In observance of World AIDS Day, HIV experts discussed the future of the epidemic with community members at the Smithsonian’s National Museum of Natural History in Washington, D.C. Co-hosted by the American Society for Microbiology, “Imagining an HIV-Free Future” was one in a series of programs related to the new exhibition, Outbreak: Epidemics in a Connected World.

The safety and dosing requirements of a new drug licensed for use by nonpregnant adults may differ for pregnant women. This has been the case for drugs for treating both HIV and tuberculosis (TB), the most common HIV co-infection. An NIH study into how pregnancy affects the body’s processing of drugs for HIV and TB has helped provide a foundation for national and international HIV treatment guidelines for women who are pregnant or have recently given birth.

HIV is a master of sneaking past our natural defenses. Typically, when the body encounters a harmful virus, immune cells recognize viral proteins and stimulate the production of antibodies. HIV, however, has evolved several ways to cloak vulnerable areas of viral proteins. A report released last month from NIAID scientists reveals new insights into one such tactic of immune invisibility.

Scientists have previously recognized that the HIV reservoir varies in size between individuals. Now, NIAID researchers and their collaborators have discovered that variations in an important viral gene may play a role in the size of one’s HIV reservoir. Their findings, reported online last week, expand scientists’ understanding of how specific attributes of the virus a person acquires can affect the course and nature of their HIV infection.
