How does friendly fire happen in the pancreas?

Scientists at Helmholtz Zentrum München have discovered a mechanism used by the immune system to prepare for attacks on insulin-producing cells in the pancreas. The team identified a signaling pathway triggered by miRNA92a, which leads to an increase in immune cells that promote autoimmunity. Targeted intervention using antagomirs may ...

EBV-derived microRNAs silence immune alarm signals of the host cell

Scientists at Helmholtz Zentrum München discovered a mechanism by which EBV virus suppresses alarm signals sent out by infected cells. MicroRNAs made by the virus block production of proteins that would ring the alarm, rendering killer T cells and helper T cells inactive.

Circulating immune cells as biomarkers for idiopathic pulmonary fibrosis

A study by Helmholtz Zentrum München found that myeloid-derived suppressor cells (MDSC) are increased in the blood of patients with idiopathic pulmonary fibrosis (IPF), correlating with lung function decline. MDSC may serve as a biomarker for IPF diagnosis and disease progression.

Cancer: Molecularly shutting down cancer cachexia

Researchers have identified AMPK as the central enzyme in cancer cachexia, a condition that results in weight loss due to metabolic complications. A peptide was developed to selectively reactivate AMPK, which has been shown to prevent increased fat breakdown and promote 'healthy' adipose tissue.

Allergy research: Response to house dust mites is age-dependent

Researchers found that an extract from house dust mites triggers different responses depending on the age of the person, with leukotrienes playing a key role in adults. The study suggests that cortisone therapy may not be effective against this type of allergy and that targeted therapies could be more effective.

Breastfeeding alters maternal metabolism and protects against diabetes

A recent study found that breastfeeding for over three months postpartum alters maternal metabolism, producing lower concentrations of branched-chain amino acids and phospholipids. This change in metabolites is linked to reduced insulin resistance and a lower risk of developing type 2 diabetes.

Ship engine emissions adversely affect macrophages

A recent study reveals that ship engine emissions adversely affect macrophages, a key component of the immune system. The toxic effects of these emissions on macrophages can lead to pro-inflammatory reactions and other biological processes, highlighting the need for efficient particle-reducing measures.

New protocol enables analysis of metabolic products from fixed tissues

A team of scientists at Helmholtz Munich developed a protocol to analyze metabolite composition in fixed tissues using mass spectrometry imaging. This method allows for the study of spatial distribution of molecules with high precision, enabling the identification of new predictive, diagnostic and prognostic markers.

MicroRNAs help to predict disease progression in brain tumors

Researchers at Helmholtz Munich have developed a new method to predict disease progression in glioblastoma patients. By analyzing four specific miRNAs, they can identify patients who are at high risk of poor treatment outcomes and may benefit from alternative or intensified treatments.

36,000 children already tested for early type 1 diabetes

The Fr1da study has detected an early stage of type 1 diabetes in 105 out of 26,760 children aged two to five years. The children have not shown signs of metabolic imbalance, suggesting a potential breakthrough in preventive healthcare. Families are being offered comprehensive support and care.

Breast cancer progression -- the devil is in the detail

Breast cancer cells challenged with a small-molecule inhibitor targeting specific invasive properties switch to an alternative mode-of-action, rendering them even more aggressive. The results suggest that inhibiting one pathway may not block all aggressiveness in breast cancer cells.

Key switch in the immune system regulated by splicing

Researchers at Helmholtz Zentrum München have identified two variants of the protein MALT1, which are regulated by posttranscriptional splicing and affect the immune response. The study found that stronger activation of T cells is associated with the MALT1A variant, while the MALT1B variant results in a weaker response.

The next step in preventing diabetes

Scientists have developed novel insulin mimetopes that can induce regulatory T cells to produce tolerance against insulin, halting the development of type 1 diabetes in young mice. In a humanized mouse model, the new vaccine efficiently stimulates regulatory T cells, which can impede the immune system's attack on insulin-producing cells.

Helmholtz researchers identify genetic switch regulating satiety and body weight

Researchers at Helmholtz Munich identified a new component regulating body weight and food intake, with histone deacetylase 5 (HDAC5) playing a significant influence on leptin's effect. The study found that HDAC5 is essential for the brain to recognize fat depot levels, enabling adaptation to food intake and reducing obesity.

ERC Consolidator Grant: Six million euros for 3 scientists at Helmholtz Zentrum Munchen

The Helmholtz Zentrum Munchen has been awarded 14 ERC grants, with three scientists receiving 6 million euros. Dr. Daniel Razansky is investigating non-invasive brain imaging methods, while Dr. Irmela Jeremias focuses on targeted tumor treatment and Dr. Mathias Heikenwaelder explores immune system interactions in liver disease.

The cellular protein shredder is impaired by cigarette smoke and in COPD patients

A study by Helmholtz Munich found that cigarette smoke damages the immunoproteasome, a protein complex responsible for degrading and presenting foreign proteins to the immune system. This impairment weakens the immune response in COPD patients, making them more prone to viral infections.

With the right algorithms: Optimizing cell cycle analysis

Scientists have developed a new method for classifying cells based on large population of cell images, allowing for high specificity and accuracy.
