IGF-1 protein may be key to prevent heart disease in older adults

As men and women grow older, their chances for coronary heart disease also increase. Atherosclerosis is a condition in which plaque builds up inside the arteries, which can lead to serious problems, including heart attacks, strokes or even death. [More]
EPFL researchers reprogram TAMs to prevent tumor metastasis

EPFL researchers reprogram TAMs to prevent tumor metastasis

One of the major obstacles with treating cancer is that tumors can conscript the body's immune cells and make them work for them. Researchers at EPFL have now found a way to reclaim the corrupted immune cells, turn them into signals for the immune system to attack the tumor, and even prevent metastasis. [More]
Epigenomic alterations play key role in triggering obesity-induced diabetes

Epigenomic alterations play key role in triggering obesity-induced diabetes

Obesity is a risk factor for developing type 2 diabetes, yet not all obese humans develop the disease. In a new study, researchers from the Karolinska Institutet in Sweden and from the Institute of Health and Medical Research in France have identified epigenomic alterations that are associated with inflammation and type 2 diabetes [More]
Lower quantities of CD74 protein in placentas of preeclamptic women can impact fetal development

Lower quantities of CD74 protein in placentas of preeclamptic women can impact fetal development

Preeclampsia is one of the most common complications to occur during pregnancy, yet its causes are still unknown. A new study involving patients, cell cultures and animal experiments has now shown that those affected by the disease have lower quantities of the placenta's immune protein CD74, and that certain inflammatory factors are higher. These factors disrupt the formation of the placenta and leave the fetus undernourished. [More]

Macrophages play key role in quick tissue repair

Macrophages play key role in quick tissue repair

While scientists have known for many years that there are cells living in the cavities surrounding various organs such as the heart, lung and liver, their function has remained unknown. A recent Cumming School of Medicine study examined these cells, and discovered they play an integral role in fast tissue repair. The study was published in the journal Cell this month. [More]
Study shows pulmonary alveolar proteinosis can be cured by single transfer of monocytes

Study shows pulmonary alveolar proteinosis can be cured by single transfer of monocytes

Researchers from VIB-UGent reveal that adult circulating monocytes that get access to the macrophage niche in the liver or the lung can acquire identical tissue-specific macrophage functions and self-maintenance capacities as macrophages of embryonic origin. [More]
Study shows beneficial effect of hNSC transplantation for TBI

Study shows beneficial effect of hNSC transplantation for TBI

Traumatic brain injury (TBI) is a major cause of mortality and morbidity, often causing lifelong disability for those who survive. Treatment is limited to supportive care, but stem cell therapy has received recent attention as a way to promote recovery for injuries to the central nervous system (CNS). In this study, researchers transplanted human neural stem cells (hNSCs) into the brains of mice modeled with TBI to investigate whether the hosts' immune systems and the stem cells acting in concert would enhance repair.

Cyclodextrin dissolves cholesterol crystals, reduces atherosclerotic plaques

Cardiovascular disease from atherosclerosis is one of the most common causes of death worldwide. Inflammation plays a crucial role in atherosclerosis and cholesterol crystals are considered to be early triggers in the development of the disease. [More]
Immunoproteasome inhibits repair function of alveolar macrophages

Immunoproteasome inhibits repair function of alveolar macrophages

Scientists of Helmholtz Zentrum M√ľnchen, a partner in the German Center for Lung Research, have observed that the immunoproteasome inhibits the repair function of alveolar macrophages. [More]
Researchers disprove previously assumed behavior of macrophage immune cells

Researchers disprove previously assumed behavior of macrophage immune cells

What happens when macrophage immune cells are activated in the course of an inflammation to combat pathogens such as bacteria or viruses? Researchers of the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg pursued this very question. The researchers discovered that the immune cells behave differently from what was previously assumed. Their metabolism upholds the production of antimicrobial substances and fatty acids during activation. In this way, they deliver important resources for the immune responses they trigger. [More]
Low bone mass higher in HIV-infected males than in females

Low bone mass higher in HIV-infected males than in females

Accumulating evidence suggests that rates of low bone mass are greater in HIV-infected males than in females. Researchers led by Grace Aldrovandi, MD, chief of the Division of Infectious Diseases at Children's Hospital Los Angeles, studied 11 biomarkers associated with inflammation, bone loss and/or bone formation in about 450 individuals - assessed by sex and HIV status - to try to determine causes of this differential bone loss.

Protein p62 acts as molecular brake to keep inflammation in check, avoid collateral damage

Protein p62 acts as molecular brake to keep inflammation in check, avoid collateral damage

Inflammation is a Catch-22: the body needs it to eliminate invasive organisms and foreign irritants, but excessive inflammation can harm healthy cells, contributing to aging and sometimes leading to organ failure and death. Researchers at University of California, San Diego School of Medicine have discovered that a protein known as p62 acts as a molecular brake to keep inflammation in check and avoid collateral damage.
