A New Way to Measure and Predict Human Immune Health
The immune system senses and responds to changes in physiologic health, and a new tool called the immune health metric (IHM) can measure and even predict some of these changes, an NIAID study has found. If doctors could use the IHM to detect health problems long before symptoms appear, they could potentially act early to prevent disease, the investigators suggest.
The Hidden Link Between Malaria and Lupus
Scientists have long been aware that malaria infection is associated with high levels of autoantibodies—antibodies that recognize and attack the person’s own tissues and are associated with autoimmune disorders. NIAID researchers, along with their colleagues, have studied the molecular mechanisms of these autoantibodies. Their findings reveal the associations between malaria, human resistance to it, and autoantibodies that are linked to certain autoimmune disorders—specifically, systemic lupus erythematosus (SLE).
Exploring the Potential of Pharmacies to Increase Access to HIV Testing
In 2022, an estimated 31,800 people were diagnosed with HIV in the United States. Although HIV incidence has declined by 12% from 2018 to 2022, many people are still undiagnosed due to limited access to HIV testing resources. This has resulted in people with HIV who are unaware of their status going without treatment and wider health inequities among racial, sexual, and gender minority communities...
Our Words Have Power—NIAID Embraces Respectful, Inclusive, and Person-First Language
by Jeanne Marrazzo, M.D., M.P.H., NIAID Director
Our institute is responsible not only for advancing scientific knowledge, but for doing so in a way that honors the dignity, individuality, and autonomy of the people affected by the health issues we address. For this reason, I am very proud to share the updated NIAID HIV Language Guide, a thoroughly vetted resource to inform our written and verbal communications.
Stepping into Science
Realizing that traditional laboratory science – aka “bench research” – isn’t for everyone, staff at NIAID's Rocky Mountain Laboratories recently invited two dozen area high school students to experience not only traditional research but also the lesser-known careers that make bench research possible.
NIAID Raises Awareness to Malaria-like Diseases in W. Africa
NIAID scientists and colleagues have identified dengue, Zika and chikungunya viruses in the West African country of Mali, where health care providers could be misdiagnosing patients as having malaria. All four infectious diseases are caused by a mosquito bite.
Antiretroviral Drug Improves Kidney Function After Transplant in People with HIV
An HIV drug that suppresses the activity of the CCR5 receptor—a collection of proteins on the surface of certain immune cells—was associated with better renal function in kidney transplant recipients with HIV compared to people who took a placebo in a randomized trial. According to the authors, these findings warrant further exploration of the benefit of CCR5 antagonists in all kidney transplant recipients regardless of HIV status. The findings of the NIAID-sponsored trial were presented today at the 2024 American Transplant Congress in Philadelphia.
Unpacking the Interplay between Autoimmunity and Immunodeficiency
The presence of antibodies that target one of the body’s own proteins was associated with severe infections that typically only occur when a person’s immune system is suppressed, based on a multi-cohort study of blood samples from more than 1,000 people. This study suggests autoimmune processes could be involved in the development of immunodeficiency in adulthood.
An Emergency Department Screening Strategy Identifies Asymptomatic and Undiagnosed Syphilis
As syphilis rates continue to rise in the United States, emergency departments may be a way for people with limited healthcare access to get screening and treatment. A NIAID study derived an emergency department syphilis screening strategy to help people get diagnosed before their infection reaches an advanced stage. This approach could reduce disease burden and prevent cases of congenital...
NIAID Research Team Develops 2nd Model of Crimean-Congo Fever
A NIAID research team has developed an additional nonhuman primate study model for Crimean-Congo hemorrhagic fever (CCHF), providing an alternative for development of critically needed vaccines and therapeutics.
NIAID Targets Transport System as Lyme Disease Treatment
NIAID scientists and colleagues are investigating a potential treatment strategy against Lyme disease that would directly suppress Borrelia burgdorferi, the bacterium that causes the disease.
Proof-of-Concept Study Shows an HIV Vaccine Can Generate Key Antibody Response in People
An HIV vaccine candidate elicited trace levels of HIV broadly neutralizing antibodies and high levels of other key immune cells in an early-stage clinical trial. This immune response is an important signal that, if antibody levels can be further amplified, the vaccination strategy might be able to prevent HIV.
NIAID Marks HIV Vaccine Awareness Day 2024
On the 27th observance of HIV Vaccine Awareness Day (Saturday, May 18), we express our gratitude to the dedicated global community of scientists, advocates, study participants, study staff, and funders working toward a safe, effective, durable, and accessible HIV vaccine.
Exploring a Meningitis Vaccine for Gonorrhea Prevention
A preventive vaccine for gonorrhea would be a major advance in public health, according to an editorial co-authored by NIAID Director Jeanne Marrazzo. The genetic sequences of the bacteria that cause gonorrhea and meningitis B, are closely related. This has led researchers to explore whether the 4CMenB vaccine, approved by the Food and Drug Administration for meningitis B, might also prevent gonorrhea. NIAID is sponsoring an efficacy study of the 4CMenB vaccine for gonorrhea prevention.
Championing Asthma Research to Reduce the Burden of Disease
Today on World Asthma Day, NIAID reaffirms its commitment to reducing illness from this chronic lung syndrome and improving quality of life for people with asthma through research that informs the development of new asthma prevention and treatment strategies. NIAID-funded studies recently uncovered new risk factors for asthma and a previously unreported cause of frequent, severe asthma attacks. Other studies shed light on poorly understood causes of airway inflammation, as well as on genes and proteins involved in regulating asthma severity.
Making an Impact: Results from an NIAID-funded Study of Hospitalized COVID-19 Patients
Why do some people hospitalized with COVID-19 succumb, while others—with apparently similar disease severity at the time of hospitalization—survive? Among older individuals, are there particular immune responses to SARS-CoV-2 virus infection that set the stage for the increased risk of severe COVID-19? New publications from the NIAID-funded IMPACC study help provide answers.
New Tool Identifies Aedes Mosquito Exposure in People
Scientists at NIAID developed a new tool to help identify geographic hot spots for Aedes mosquitoes, a type of mosquito that can spread diseases such as dengue, Zika and chikungunya. The tool uses a marker from blood serum to identify people bitten by Aedes mosquitoes. Monitoring for this marker in blood samples could help find sites where disease-carrying mosquitoes live, allowing for targeted interventions against dengue and other diseases.

The HIV Field Needs Early-Stage Investigators (VIDEO)
by Jeanne Marrazzo, M.D., M.P.H., NIAID Director
The HIV research community is led by scientists with deep personal commitments to improving the lives of people with and affected by HIV. Our collective decades of work have generated HIV testing, prevention and treatment options beyond what we could have imagined in the 1980s. Those advances enable NIAID to explore new frontiers: expanding HIV prevention and treatment modalities, increasing understanding of the interplay between HIV and other infectious and non-communicable diseases, optimizing choice and convenience, and building on the ever-growing knowledge base that we need to develop a preventive vaccine and cure. The next generation of leaders will bring these concepts to fruition, and we need to welcome and support them into the complex and competitive field of HIV science.
