A tiny invader, perhaps a virus or a microbe, enters the body, and our ancient immune system responds. But how does it know what kind of invader has landed? And once it knows, how does it decide what kind of immune response it should launch?
In humans, the immune system consists of two parallel systems working with one another to fend off invaders. One is the innate immune system, the other the adaptive immune system.
Immunologist Bali Pulendran studies how those two systems work together to identify and respond to all kinds of intruders including pathogens, viruses and microbes.
Itâ€™s the innate immune systemâ€™s job to recognize the first signs of infectionâ€”that is, the moment a pathogen enters the body. â€œIn a sense they act as smoke detectors if you will,â€ says Pulendran. â€œLittle alarms.â€
Riders gather at the Hope Clinic of the Emory Vaccine Center for the final leg of their ride.
More than 130 bicyclists rode 200 miles in two days to raise $188,660 for AIDS vaccine research at the Emory Vaccine Center. The AIDS Vaccine 200 on May 22-23, sponsored by Action Cycling Atlanta, was the eighth annual ride. The series now has raised more than $680,000 for AIDS vaccine research.
This year’s riders traveled from Emory to Eatonton, Georgia, and back to Emory along with a volunteer crew.
Because of generous sponsorships, Action Cycling donates 100 percent of funds raised by participants to AIDS vaccine research. These unrestricted funds fill gaps that cannot be met by grant dollars alone.

Although African Americans make up a significant share of HIV cases in the U.S., they are underrepresented in HIV clinical trials. New research shows that promotion of HIV clinical trials and participation by African Americans can be increased by coalitions that link community organizations to clinical-research institutions.
â€œCommunity organizations already have built trusting relationships in their communities,â€ saysÂ Paula Frew, PhD, assistant professor of medicine at Emory School of Medicine. â€œIf HIV/AIDS prevention and HIV clinical research become part of the agendas of these organizations, they can become ideal allies for increasing participation by community members who are at risk for disease.â€
Frew was lead investigator in a study published recently in the Journal Prevention Science. SheÂ is director of health communications & applied research at the Hope Clinic of the Emory Vaccine Center and an investigator in the Emory Center for AIDS Research (CFAR).
