A study by UNC researchers confirms the presence of mutated, drug-resistant human immunodeficiency virus in the semen of men taking antiviral medications. The study found that if men do not have adequate suppression of their virus, they are likely to shed drug-resistant strains of HIV in their genital secretions.
Researchers have discovered a gene called E2F1 that helps bring about tumor cell death yet is also necessary for their growth. The study found that without E2F1, tumors grew slower but cell death was reduced by 80 percent.
Researchers at UNC Health Care found that allergy increases susceptibility to otitis media, a common ear infection in young children. Antihistamine treatment may help alleviate symptoms.
Researchers found that blocking beta-adrenergic receptor kinase (BARK) can prevent heart failure in mice genetically engineered to develop the disease. The study suggests a fundamental abnormality in the beta-adrenergic receptor system is at the root of causing heart failure.
Researchers at UNC Health Care have discovered two proteins, CRY1 and CRY2, which help regulate circadian rhythms. These proteins were found in layers of the retina not involved in forming visual images, and their presence may help set the daily clock from sites in skin cells.
