What Does an Immunologist Do?

February 12, 2024
This post is part of a miniseries on the immune system. Be sure to check out the other posts in this series that you may have missed.

Immunology is the study of the immune system, including all the cells, tissues, and organs that work together to protect you from germs. A person who studies immunology is called an immunologist, and there are three types:

  • Researchers, who study the immune system in the laboratory to understand how it works or how it can go awry and find new treatments for immune system-related diseases
  • Doctors, who diagnose and care for patients with diseases related to the immune system, such as food allergies or immunodeficiency
  • Physician-scientists, who are both researchers and doctors and divide their time between the clinic and the laboratory

Spotlighting SEPA for National STEM Day

November 8, 2023

The NIGMS Science Education Partnership Award (SEPA) program provides opportunities for pre-K-12 students from underserved communities to access STEM educational resources. SEPA grants support innovative, research-based, science education programs, furthering NIGMS’ mission to ensure a strong and diverse biomedical research workforce. SEPA projects generate resources that are mapped to state and national teaching standards for STEM and are rigorously evaluated for effectiveness; most are also available at no cost. These resources include mobile laboratories, interactive health exhibits in museums and science centers, educational resources for students, and professional development for teachers. Projects engage students and encourage them to envision themselves having careers in biomedical research.

To celebrate National STEM Day, we’re taking a look back at some of the SEPA projects we’ve recently featured on the blog, as well as our STEM teaching resources website, which includes several SEPA-funded materials. Check out the snapshots of each of the projects with links to the full articles and the teaching website below.

Quiz: Sepsis Science

At least 1.7 million adults in the United States develop a life-threatening condition called sepsis each year. Sepsis is an overwhelming or impaired whole-body immune response that’s most often caused by bacterial infections. However, it can also be caused by viral infections, such as COVID-19 or influenza; fungal infections; or other injuries, including physical trauma.​​ Anyone can get sepsis, but there’s a higher risk for some people, such as those who are ages 65 and older, who have certain medical conditions, or who have recently experienced severe illness or hospitalization.

The early symptoms of sepsis can include fever, chills, rapid breathing or heart rate, disorientation, and clammy or sweaty skin. Because other conditions also have these symptoms, sepsis can be difficult to diagnose. NIGMS-supported researchers are working to increase our understanding of sepsis so that doctors can identify it more quickly and treat it more effectively.

Sepsis Sleuths

September 13, 2022

Sometimes we can be our own worst enemies without even realizing it. One devastating example is sepsis: our body’s overwhelming or impaired immune response to an insult—usually an infection or an injury to the body. According to the Centers for Disease Control and Prevention (CDC), sepsis affects at least 1.7 million people in the United States each year, and it can lead to tissue damage, organ failure, and death. (See our sepsis fact sheet for more information.)

Could a Spoonful of Sugar Be a Medicine?

Large sugar molecules called glycans coat every cell in our bodies. They can also be found inside and between cells, and they are important for many biological processes, including how our cells interact with one another and with pathogens. For example, glycans on red blood cells determine blood type, and those on the cells of organs determine whether a person can receive a transplant from a particular donor. Scientists have only begun to explore sugars’ complexities and potential uses. Here, we look at the contributions three NIGMS-supported researchers are making to glycoscience.

Human Milk Sugars

Glycans called human milk oligosaccharides (HMOs) make up a significant portion of human milk. Study findings have shown that some HMOs can be prebiotics—substances that encourage beneficial bacteria to grow. Research has also revealed that some disease-causing microbes bind to certain HMOs, potentially allowing the germs to pass through the body without causing illness.

Fight Against COVID-19 Aided by Sepsis Researchers

Since the start of the COVID-19 pandemic, researchers from many areas of biomedical science have worked together to learn how this new disease affects the human body, how to prevent its spread, and how to treat it. Severe cases of COVID-19 and cases of sepsis share many symptoms. Sepsis is the body’s overactive and extreme response to an infection. It’s unpredictable and can progress rapidly. Without prompt treatment, it can lead to tissue damage, organ failure, and death.

Sepsis has similarities with some cases of COVID-19, most likely because the two conditions trigger the same reactions at the cellular level. Researchers have studied these reactions in sepsis for many years.

“When we look back on 2020 and the speed with which progress was made against COVID-19, two features will stand out,” says John Younger, M.D., a member of the NIGMS Advisory Council who recently co-chaired a working group on advancing sepsis research. “The first is how quickly the biotechnology community came together to develop vaccine candidates. The second, and arguably the most immediately impactful, is how caregivers and clinical researchers were able to rapidly refine the care of COVID-19 patients based on decades of experience with sepsis."

This post highlights a few of the many sepsis researchers supported by NIGMS who are applying their expertise to COVID-19.
