Interferon-gamma essential for lung-resident memory B cell development after influenza infection

During a bout of influenza, B cells interact with other immune cells and then take different paths to defend the body.

Study helps explain why solid tumors often spread to the spine

The vertebral bones that form the spine are derived from a distinct type of stem cell that secretes a protein favoring tumor metastases, according to a study led by researchers at Weill Cornell Medicine.

A family of weird proteins hijacks plants’ cellular plumbing

Many of the bacteria that ravage crops and threaten our food supply use a common strategy to cause disease: they inject a cocktail of harmful proteins directly into the plant's cells.

Cerebellar inhibitory interneurons essential for fear memory, study finds

An LSU Health New Orleans research study led by Siqiong June Liu, PhD, Professor of Cell Biology and Anatomy, has found that cerebellar inhibitory interneurons are essential for fear memory, a type of emotional memory formation.

Microbiome composition influences severity of Legionnaires' disease

Pneumonia is an infection of the lung alveoli caused by bacteria, viruses or fungi. It is one of the leading causes of morbidity and mortality worldwide, representing a clinical and economic burden and a global public health problem.

Arf1 inhibition induces tumor regression by promoting T cell infiltration

In recent years, cancer immunotherapies, represented by immune checkpoint blockade (ICB), have been highly successful and have become an important basis for the future treatment of cancers.

Chemotherapy drug may promote cancer growth by injuring surrounding cells

A standard chemotherapy drug injures surrounding non-cancer cells, which can then awakens dormant cancer cells and promotes cancer growth, according to a new study publishing September 12th in the open access journal PLOS Biology by Ramya Ganesan of Emory University, US, and colleagues.

Mount Sinai researchers identify the structure of a special red blood cell transporter

Researchers at the Icahn School of Medicine at Mount Sinai have identified the structure of a special transporter found in red blood cells and how it interacts with drugs.

New test could detect brain tumors using cerebrospinal fluid

Researchers with the Johns Hopkins Kimmel Cancer Center, the Johns Hopkins University School of Medicine and four other institutions have developed a molecular test to identify the presence of brain tumors by measuring abnormal genetic material shed by tumors and circulating in cerebrospinal fluid (CSF).

Elevated pressure in the bile canaliculi alters structure of the liver tissue

The liver produces bile, which the intestine uses for digestion. For the transport of bile, the liver relies on a network of microscopic tubings, known as bile canaliculi, formed by liver cells called hepatocytes.

Scientists discover thymic M cells

It came as a surprise to Professor David Lo and his graduate student Diana Del Castillo when they were recently consulted by researchers in Israel for their expertise on specialized cells called Microfold cells, or M cells, which are mostly known for their presence in the intestinal epithelium.

Immune cells can create their own chemical cues to navigate in complex environments

Human immune cells are capable of coordinating their own movement more independently than previously thought. InFLAMES researcher Jonna Alanko has discovered that immune cells do not just passively follow the chemical cues in their environment.

Aging reorganizes pancreas circadian transcriptome

A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 16, entitled, "Reorganization of pancreas circadian transcriptome with aging."

Cornell biologists shine light on the possible origin of differences in human social behaviors

Male fruit flies don't usually like each other. Socially, they reject their fellow males and zero in on the females they discern via chemical receptors – or so scientists thought.

Scientists develop new technique to study sugars on immune cells

Everyone loves a sweet treat, even our cells. While we typically think of sugar as a component of our diet that gives us energy, sugars are also very important in guiding the activity of our cells.

Mutational changes in Avian flu virus could increase risk of transmission to humans

A new study from researchers in China and Nottingham has discovered that a subtype of avian flu virus, endemic in poultry farms in China, is undergoing mutational changes, which could increase the risk of the disease being passed on to humans.

Study sheds light on immune cells' ability to collectively migrate through complex environments

When fighting disease, our immune cells need to reach their target quickly. Researchers at the Institute of Science and Technology Austria (ISTA) now discovered that immune cells actively generate their own guidance system to navigate through complex environments.
