PFAS chemical helps suppress the neutrophil respiratory burst, study finds

In a new study, researchers found that the PFAS chemical GenX suppresses the neutrophil respiratory burst – the method white blood cells known as neutrophils use to kill invading pathogens.

LJI receives funding from NIAID to lead the biggest human immunoprofiling effort

A new grant of over $17 million from the National Institute of Allergy and Infectious Diseases (NIAID) has established La Jolla Institute for Immunology (LJI) as the leading institute for human immunology data curation, analysis, and dissemination. With this funding, LJI has taken the helm of the Human Immunology Project Consortium Data Coordinating Center, a critical tool in the effort to fuel scientific collaboration in immunoprofiling and highlight findings from the overall Human Immunology Project Consortium (HIPC).

The essential protein needed for immune evasion and tumor cell metabolism

Typically, tumor cells change their energy metabolism and take in more glucose to enable their rapid division and spread. As a result, the body’s immune response to cancer is suppressed by limiting the immune cells’ access to glucose.

How the immune response in the brain aggravates epilepsy

Biologists at the University of Iowa have conclusively connected epilepsy with the brain’s immune system.

IGSF3-mediated potassium dysregulation drives glioma-related epilepsy

Glioma is one of the most aggressive malignant primary brain tumors. A common feature of glioma is the presence of localized, intermittent seizures referred to as glioma-related epilepsy, which is known to promote tumor growth. However, the mechanism involved at the molecular level is still not clear.

Inhibiting astrocyte hyperactivity can reverse cognitive deficits associated with social deprivation

Here is an important reason to stay in touch with friends and family: social isolation causes memory and learning deficits and other behavioral changes.

3D structure of a major protein complex in cilia revealed

Researchers at St. Jude Children’s Research Hospital have solved the 3D structure of an important protein complex in cilia, which are signaling appendages found on cells. The structure was pictured at the highest resolution available at the time.

Analyzing the immune microenvironment around Hodgkin lymphoma tumors

The most detailed study of Hodgkin lymphoma, a type of blood cancer, has offered considerable insight into what tumor cells must do to sustain. The Wellcome Sanger Institute discovered that cancer cells utilize signals to attract specific types of immune cells and direct them not to attack.

Research provides insight into the regulation of heartbeats

UT Southwestern Medical Center researchers have mapped gene control elements in specialized cardiac cells responsible for coordinating heartbeats. The findings of the genome exploration study, published in The Journal of Clinical Investigation, provide insight into how heartbeats are regulated and could impact diagnosis and risk prediction for a variety of common arrhythmias.

Two-step screening of aroma compounds reveals a novel and effective modulator of dendritic cells

Dendritic cells (DCs) are important players of the immune system with important functions such as the identification of infectious pathogens, production of cytokines (chemical signalers of the immune system), presentation of antigens to activate T-cells, and more.

A treatment strategy to hasten cancer cell death

Gene mutations are the cause of cancer. Tumor suppressors and oncogenes are the two main groups of these altered genes in cancer. Mutations in oncogenes can drive cell proliferation, pushing the gas pedal to the floor, whereas mutations in tumor suppressor genes can cause tumors to grow unchecked—a situation in which there is no control.
