Analyses of DNA tags may lead to better understanding of treatment approaches for cancers

Cell-free DNA (cfDNA) shed into the blood was discovered in the late 1940s but with rapid advances in genomics and computational analytics in just the past few years, researchers at Georgetown Lombardi Comprehensive Cancer Center now believe that studying tags, or modifications to this type of DNA, may lead to a better understanding of how to assess, and possibly modulate, treatment approaches for cancer and other diseases.

T cell-depleted macaques can mount potent memory responses against SARS-CoV-2

New research conducted in monkeys reveals that T cells are not critical for the recovery of primates from acute COVID-19 infections.

Pushing organ-on-a-chip microdevices to new levels to improve ovarian cancer treatment

In the evolving field of cancer biology and treatment, innovations in organ-on-a-chip microdevices allow researchers to discover more about the disease outside the human body.

Study employs llama nanobodies to hunt human cytomegalovirus

Researchers created a “nanobody”, a small fragment of a llama antibody, that can evade human cytomegalovirus as it hides away from the immune system.

Stiffness of protein fibers plays a key role in controlling cell movement, study shows

A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells.

Cell-analysis method could pave the way for new strategies to fight tuberculosis

A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.

Largest study identifies causal genetic variants associated with type 1 diabetes risk

Scientists have completed the largest and most diverse genetic study of type 1 diabetes ever undertaken, identifying new drug targets to treat a condition that affects 1.3 million American adults.

Study reveals SARS-CoV-2 variant is less sensitive to inhibition by antibodies

SARS-CoV-2 is still a major threat to humankind. The constant emergence of variants makes the threat made by the virus difficult to estimate. The SARS-CoV-2 variant B.1.617 spread in India and gave rise to the Delta variant, B.1.617.2, which is now dominant in numerous countries.

SARS-CoV-2 variant B.1.617 can infect lung and intestinal cells more efficiently than the original virus

SARS-CoV-2 still poses major challenges to mankind. The frequent emergence of mutant forms makes the threat posed by the virus difficult to predict.

New study uncovers how enterococcal cytolysins affect cells

Although Enterococcus faecalis is usually an innocuous member of the bacterial community in the human gut, it can also cause several infections, including liver disorders. The bacteria produce cytolysins, which are molecules that destroy cells. In a new study, researchers have uncovered how they do so.

Scientists provide insights on immune evasion of metastatic cancer cells in lymph nodes

Lymph nodes are critical to the body's immune response against tumors but paradoxically, cancer cells that spread, or metastasize, to lymph nodes can often avoid being eliminated by immune cells.

New multimodal diagnostic can detect cancer cells and pinpoint tumor location

Most of the tests that doctors use to diagnose cancer -- such as mammography, colonoscopy, and CT scans -- are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.
