Immunotherapy Response in Advanced Melanoma: Effect of Previous Treatments

According to a study conducted by UCLA, patients with advanced melanoma responded differently to PD-1 checkpoint blockade immunotherapy depending on a variety of variables, including whether or not they had previously received CTLA-4 blockade, another type of immunotherapy.

Study Establishes Two Distinct Regulatory T Cell Populations

According to a recent study headed by the Children’s Hospital of Philadelphia (CHOP), a regulatory class of human T cells is descended from two distinct origins, one related to autoimmunity and one related to protective immunity.

Researchers Identify Antibody that may Block Infection by All Dominant SARS-CoV-2 Variants

A team led by researchers at Weill Cornell Medicine, the University of Wisconsin-Madison; Scripps Research and the University of Chicago has identified an antibody that appears to block infection by all dominant variants of the virus that causes COVID-19, including Omicron, the most recent.

The “Hangry” Stage of Bacteria Cells

The word “hangry” describes individuals who become angry due to hunger. According to a recent study by Adam Rosenthal, PhD, an assistant professor in the department of microbiology and immunology, some bacteria cells experience hangry and release toxic substances into the body when they are denied certain nutrients.

Dengue Viruses Subvert Mosquito Biology to Tamp Down Human Immune Responses

The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.

Endothelial Deletion of Wt1 Gene During Coronary Vessel Formation Affects Embryonic Heart Development

How is the mammals' heart formed? What role do endothelial cells play? Do the same pathways and genes involved in the formation of the embryonic heart also play a role in repair processes?

Novel inhibitor, hopeaphenol, blocks HIV expression

In the United States, around 1.2 million people are living with HIV as of 2022. Many of these people can now live productive, symptom-free lives thanks to antiretroviral therapies, but a solution that permanently removes HIV from an infected person’s body is still a long way off.

Additional therapeutic maneuver may be needed to stop some metastasized tumors Cancer That...

Cancer that has spread to areas like the lungs can apply the brakes to a natural pathway that should recruit killer T cells directly to where it has metastasized, scientists report.

Wearable microscopes produce real-time images of mouse spinal cord activity

The spinal cord acts as a messenger, carrying signals between the brain and body to regulate everything from breathing to movement.

Blunted inflammatory response in obese individuals responsible for susceptibility to severe COVID-19

Individuals who are obese may be more susceptible to severe COVID-19 because of a poorer inflammatory immune response, say Cambridge scientists.

Identifying the underlying causes of rare genetic immune disorders

The activated PI3K Delta syndrome 2 (APDS2) is a rare genetic disease that is caused by cellular anomalies, according to experts from the Garvan Institute of Medical Research.

Researchers discover a new intracellular "smoke detector"

Researchers at the Universities of Bonn and Singapore have discovered a new intracellular "smoke detector." The sensor warns of damage to the mitochondria - the microscopic power plants that supply the cell with energy.

Stem cells must take out the trash to protect against age-related diseases

In humanity's ongoing quest for the elixir of life, the science keeps pointing to stem cells. Research increasingly shows that maintaining stem cell fitness promotes a long healthspan, and new findings show keeping stem cells clean and tidy is an integral step.

Novel tool analyzes how immune cells respond to SARS-CoV-2 vaccination

A study discovered that the magnitude and quality of a key immune cell’s response to two doses of the Pfizer-BioNTech COVID-19 vaccine were significantly lower in individuals with earlier SARS-CoV-2 infection compared to individuals without previous infection.

T cell-driven changes in the gut may affect brain function associated with depression

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression.

Macrophages likely to be a potential target for ER+ breast cancer

Most immunotherapies that aim to increase T cell activity are ineffective in treating estrogen receptor-positive (ER+) breast cancer. A new study of invasive ER+ breast cancers led by researchers at the University of Pittsburgh School of Medicine implies that targeting a different type of immune cell called macrophages may be a more effective approach.
