Immune system suppression may be related to problem drinking

Cytokines are small proteins in the immune system that act as chemical messengers between cells. Prior research suggests that pro- and anti-inflammatory cytokines are dysfunctional during alcohol dependence and may contribute to the progression from healthy to problem drinking. This study compared social and non-dependent problem drinkers on the impact of alcohol-related changes in the body's immune response to stress, alcohol-cue induced craving and anxiety, motivation to drink, and alcohol consumption.

Surprise finding leads to new insights into splenic B cell differentiation

Belgian scientists have discovered the key role of protein Taok3 in the development of type B immune cells known as MZB cells, which are responsible for making antibodies to fight diseases. Researchers are familiar with the functions of MZB cells, but the molecular processes involved in their development remained a mystery until an unrelated test revealed that Taok3 plays an essential role. Using these insights, a research team led by professor Bart Lambrecht (VIB-UGent/UZ Gent) demonstrated that mice genetically lacking in Taok3 did not develop MZB cells, and are more susceptible to bacterial infection. These insights also lead to potential new molecular therapies for genetic conditions, asthma and diabetes. The results of the study were published in leading academic journal Nature Immunology.

Unexpected experimental results indicate nicotine creates a chronic drug memory in the brain

ISBM releases the updated version of Immune Response Template

Drug development has always been expensive and complicated. Many drug candidates are discontinued from clinical development during later stages, and it is not always possible to determine doses of medication or recruit a suitable group of patients for trials. ISBM offers a new approach to solve these problems: quantitative systems pharmacology (QSP) modeling. Diseases and biological systems are modeled in the most precise mechanistic way, and equations are based on data and basic knowledge. QSP models have the greatest planning horizon; applied during the early stages of research, they predict what the developers will observe during the second phase of clinical trials.

Salicylic acid promotes nasal mucosa colonization by Staphylococcus aureus

Salicylic acid is a plant hormone best known for its use as a key ingredient in pain relievers, anti-acne preparations and medications for skin conditions. We also consume mild doses of salicylic acid when we eat fruits and vegetables. An international team of researchers, including scientists from Vetmeduni Vienna, has now shown that this multifaceted compound can also have an unpleasant side effect. Salicylic acid forms complexes with iron, an important trace element for humans as well as bacteria. Laboratory tests showed that iron limitation strongly promotes the formation of biofilms by Staphylococcus aureus. This allows the bacteria to survive and persist in our respiratory tract for longer periods of time which eventually trigger life-threatening infections in immunocompromised persons. The study was published in the journal Frontiers in Microbiology.
