Study shows antibody levels drop rapidly in recovering COVID-19 patients

The lack of effective treatments for COVID-19 is forcing hospitals to use blood plasma from recovering patients to treat those who have severe symptoms.

Key blood marker could offer the most effective treatment for melanoma

An Edith Cowan University (ECU) study has revealed that a key blood marker of cancer could be used to select the most effective treatment for melanoma.

New technology rapidly diagnoses sickle cell disease

Researchers at the University of Colorado Boulder and the University of Colorado Anschutz Medical Campus have developed a new way to diagnose diseases of the blood like sickle cell disease with sensitivity and precision and in only one minute.

Lymphocytes play crucial role in controlling virus shedding in asymptomatic COVID-19 patients

COVID-19 remains stubbornly inconsistent. More than a million people have died and 35 million have been diagnosed, but a large fraction of people infected with the coronavirus--about 45%, according to recent estimates--show no symptoms at all.

Researchers demonstrate healing power of extracellular vesicles on a heart-on-a-chip

Extracellular vesicles (EVs) -- nanometer sized messengers that travel between cells to deliver cues and cargo -- are promising tools for the next generation of therapies for everything from autoimmune and neurodegenerative diseases to cancer and tissue injury.

Army researchers test alternative ways to measure COVID-19 antibody levels

Researchers with the U.S. Army Futures Command are part of a team that tested alternative ways to measure COVID-19 antibody levels, resulting in a process that is faster, easier and less expensive to use on a large scale. Their method holds promise for accurately identifying potential donors who have the best chance of helping infected patients through convalescent plasma therapy.

Scientists find sensor protein which enables normal functioning of bladder

A team co-led by scientists at Scripps Research has found that the main sensor protein enabling our sense of touch also underlies the feeling of having a full bladder and makes normal bladder function possible.

Immune failure can cause serious COVID-19

While most people dying from COVID-19 are elderly, up to 5-10% of younger adults and children can also be seriously infected by the SARS-CoV-2 virus.

Researchers unravel molecular factors that drive severity of COVID-19

While most COVID-19 cases are asymptomatic or mild, severe complications associated with acute respiratory distress have led to more than one million deaths worldwide in just several months.

Study shows lasting immunity offered by SARS-CoV-2 antibodies

One of the most significant questions about the novel coronavirus is whether people who are infected are immune from reinfection and, if so, for how long.

Immunotherapy using CAR NKT cells shows promise for treating solid tumors

Natural killer T (NKT) cells, a type of immune cells known for their potent anti-cancer properties in murine tumor models, have been developed into a novel form of immunotherapy to treat patients with cancer.

Dynamic map shows how immune cells fight microbes and remember future infections

Scientists have plotted the activity of an unlimited number of genes in the immune cells of mice over the course of an infection.

VAV1 gene mutations may promote growth of T-cell tumors in laboratory mice

Life is an exquisite orchestration of growth and change, with checks and balances that fine-tune complex entwined interactions, both intrinsic and external.

Scientists develop new antimicrobial molecules from toxic proteins in wasp venom

A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom.

Research focuses on understanding production of memory B cells and immune responses

The current COVID-19 climate has made vaccines, antibodies, and immune responses topics of everyday conversation. Now, it isn't just immunologists who want to know how our bodies respond to re-infections months, years, or sometimes decades after an initial immune response.

Study clarifies role of ERβ in growth and regeneration of skeletal muscle in female mice

Researchers at Kumamoto University, Japan generated mice lacking the estrogen receptor beta (ERβ) gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice.

Stem cells that promote bone repair can also generate arthritic bone spurs

The same stem cells that heal broken bones can also generate arthritic bone spurs called osteophytes, according to a new study in the Annals of the Rheumatic Diseases.

Researchers trace neurons in mosquitoes that sense blood's distinctive flavor

It's one of the world's deadliest animals, and it has a taste for human blood: the mosquito. Mosquitoes spread diseases like malaria, dengue, and yellow fever that kill at least a half a million people each year. Now researchers are learning what humans taste like to mosquitoes, down to the individual neurons that sense blood's distinctive, delectable flavor.
