Adipose tissue plays key role in the aggravation of COVID-19

There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals.

Biologists unravel how tissue geometry influences cell migration

Cells move constantly throughout our bodies, performing myriad operations critical to tissue development, immune responses, and general wellbeing. This bustle is guided by chemical cues long studied by scientists interested in cellular migration.

Study shows memory T cells are formed earlier than previously thought

A person will acquire immunity to a specific disease when T cells develop into memory cells after making contact with pathogens.

Researchers discover new ways to block the colonization and spread of tumor cells

What role do the lymphatic vessels play in the metastasis of cancer cells? Scientists from the German Cancer Research Center and the Mannheim Medical Faculty of the University of Heidelberg developed a method to investigate this question in mice.

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.

Severe cases of COVID-19 resemble systemic lupus erythematosus

Scientists from Emory Health Sciences have been observing an intense stimulation of immune cells in severe cases of COVID-19 disease. This activation of immune cells is similar to acute flares of systemic lupus erythematosus (SLE)—an autoimmune disease.

Study shows removal of specific gene makes poxviruses harmless

According to a new study, the removal of a single gene makes poxviruses—a lethal family of viral infections that spread from animals to humans—harmless.

New 3D hydrogels show promise in cancer immunotherapy

A group of researchers have developed new hydrogels that make it possible to culture T lymphocytes or T cells found in the immune system.

Study uncovers how the immune system generates effective antibodies

An in-depth Garvan study of how the immune system generates effective antibodies provides new insights for vaccine design.

Cytokine storms in COVID-19 patients may prevent the development of long-term immunity

Shiv Pillai, MD, Ph.D., investigator in the Ragon Institute of MGH, MIT and Harvard and professor at Harvard Medical School (HMS), recently published a paper in Cell showing that that high levels of some cytokines seen in COVID-19 patients, as part of a cytokine storm, may prevent the development of long-term immunity to SARS-CoV-2, the virus that causes COVID-19.

Study reveals a mechanism for lower-quality immune response in patients with severe COVID-19

The release of massive amounts of proteins called cytokines can lead to some of the most severe symptoms of COVID-19.

Study reveals why immunity boost from seasonal flu vaccines is not long lasting

A study from Emory Vaccine Center provides insights into why the boost in immunity from seasonal flu vaccination lasts for months but not years, unlike some childhood vaccinations.

Detecting rare circulating tumor cells

Metastasis - the development of tumor growth at a secondary site - is responsible for the majority of cancer-related deaths.

Epigenomic data can help characterize genes that play key role in cancer progression

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually lead the tumor to metastasize and spread elsewhere in the body.
