Current treatments for tuberculosis (TB) are very effective in controlling TB infection caused by Mycobacterium tuberculosis (Mtb). They don’t, however, always prevent reinfection. Why this happens is one of the long-standing questions in TB research. A team of scientists may have found the answer… in the gut. Source: Anti-TB drugs can increase risk of TB […]

Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal axons — threadlike projections — to successfully reach their destinations in the body. Now, researchers discover how neurons navigate a tricky cellular environment by […]

More and more products carry ethical labels such as fair-trade or organic, which consumers view positively. Nevertheless, the sales figures of these products often remain low, even though they offer advantages for the environment or for society. A team of scientists have investigated what factors influence consumers’ purchasing intentions. Source: How the 'good feeling' can […]

In a surprising finding, researchers showed the protein NLRP6 aggravated the difficult symptoms of gastrointestinal graft-vs.-host disease. Knocking out this protein in mice led to significantly better survival and less severe GVHD. Source: A protein's surprising role offers clues to limit graft-vs.-host disease

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed medication for major depressive disorder (MDD), yet scientists still do not understand why the treatment does not work in nearly thirty percent of patients with MDD. Now, researchers have discovered differences in growth patterns of neurons of SSRI-resistant patients. The work has implications for depression […]
