Some cancer cells don't die; they go quiet, like seeds lying dormant in the soil. These "sleeper cells," scattered throughout the body, can stay inactive for years. But when the body faces a ...

Killer immune cells destroy cancer cells and cells infected by virus. These CD8 + T cells are activated after detection of viral infection or growth of “non-self” tumor cells. However, in chronic ...

A new research paper was published in Volume 18 of Aging-US on February 8, 2026, titled "Single-cell transcriptomics reveal intrinsic and systemic T cell aging in COVID-19 and HIV." In this study, ...

The difficulty is that EBV lives latently in B cells in the blood at a frequency, in most immunocompetent individuals, of about 1 in 100,000 to 1 in a million. That level of infection is below the ...

Scientists have discovered that T cells -- white blood cells that can destroy harmful pathogens -- can completely prevent viral infection, to an extent previously thought only possible due to ...

The worry that breast cancer may someday return is a troubling source of anxiety for many survivors of the disease. It’s understandable why, since most relapses and metastatic cancers (cancers that ...

The study demonstrated a substantial clinical burden from multiple viral infections in recipients of allogeneic hematopoietic cell transplants — especially among patients with cytomegalovirus (CMV) ...

Scientists from Duke-NUS Medical School and the Singapore General Hospital have discovered that T cells-white blood cells that can destroy harmful pathogens-can completely prevent viral infection, to ...

Scientists discover how yellow fever and encephalitis viruses enter human cells, and block them with decoy molecules.

A resurfaced video claims chickenpox vaccination fuels shingles outbreaks. Studies show shingles is less common among vaccinated kids.

A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...

Clusters of T cells, that are part of our immune system protecting us against harmful pathogens, under a microscope. By studying them, Duke-NUS scientists have found that T cells can independently ...
