New research offers insight about the reason mitochondrial DNA is maternally inherited

New research provides insight about the bedrock scientific principle that mitochondrial DNA - the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body - is exclusively passed down by the mother.

Researchers discover backup protein quality control mechanism

Researchers from the Babraham Institute, UK, and the German Center for Neurodegenerative Diseases (DZNE) have identified a backup mechanism of protein quality control which prevents the toxic effects of protein aggregation in specific tissues when normal methods of molecular monitoring fail.

Research suggests laminin could play role in slowing progression of breast tumors

Cells are capable of translating mechanical changes into biological responses. This process is known as mechanotransduction and plays a fundamental role in the progression of solid tumors, such as breast cancer.

Rasip1 gene found to be intimately involved in the creation of blood cells

Blood has long been a symbol of life and health, so it may be surprising that some aspects of blood production, i.e., hematopoiesis, remain incompletely understood.

Dormant HIV reservoirs can spontaneously produce RNA and proteins, study finds

HIV anti-retroviral therapy is considered a treatment and not a cure because patients usually carry a reservoir of HIV-infected cells that can re-emerge if treatment stops.

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.

Smoking can accelerate the process of aging, study shows

A study of nearly 500,000 people has shown that smoking shortens the end fragments of chromosomes in the white blood cells of our immune systems.

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.

3D bioprinting methods for fabricating bioengineered blood vessel models

A review paper by scientists at the Chonnam National University summarized the recent research on bioprinting methods for fabricating bioengineered blood vessel models.

Study unveils a potential solution to combat age-related immune system decline

As we age, our bodies face numerous challenges, including a decline in immune system function and an increased vulnerability to various health issues.

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.
