• Splenic leukocytes define the resolution of inflammation in heart failure

  06-03-2018 19:55 via stke.sciencemag.org
  Inflammation promotes healing in myocardial infarction but, if unresolved, leads to heart failure. To define the inflammatory and resolving responses, we quantified leukocyte trafficking and specialized proresolving mediators (SPMs) in the infarcted left ventricle and spleen after myocardial infarction, with the goal of distinguishing inflammation from its resolution. Our data suggest that the spleen not only served as a leukocyte reservoir but also was the site where SPMs were actively generate

• Inflammatory but not mitogenic contexts prime synovial fibroblasts for compensatory signaling responses to p38 inhibition

  06-03-2018 19:55 via stke.sciencemag.org
  Rheumatoid arthritis (RA) is a chronic inflammatory disorder that causes joint pain, swelling, and loss of function. Development of effective new drugs has proven challenging in part because of the complexities and interconnected nature of intracellular signaling networks that complicate the effects of pharmacological interventions. We characterized the kinase signaling pathways that are activated in RA and evaluated the multivariate effects of targeted inhibitors. Synovial fluids from RA patien

• cAMPr: A single-wavelength fluorescent sensor for cyclic AMP

  06-03-2018 19:55 via stke.sciencemag.org
  Genetically encoded fluorescent sensors enable cell-specific measurements of ions and small molecules in real time. Cyclic adenosine monophosphate (cAMP) is one of the most important signaling molecules in virtually all cell types and organisms. We describe cAMPr, a new single-wavelength cAMP sensor. We developed cAMPr in bacteria and embryonic stem cells and validated the sensor in mammalian neurons in vitro and in Drosophila circadian pacemaker neurons in intact brains. Comparison with other s

• A role for corticotropin-releasing factor signaling in the lateral habenula and its modulation by early-life stress

  06-03-2018 19:55 via stke.sciencemag.org
  Centrally released corticotropin-releasing factor or hormone (extrahypothalamic CRF or CRH) in the brain is involved in the behavioral and emotional responses to stress. The lateral habenula (LHb) is an epithalamic brain region involved in value-based decision-making and stress evasion. Through its inhibition of dopamine-mediated reward circuitry, the increased activity of the LHb is associated with addiction, depression, schizophrenia, and behavioral disorders. We found that extrahypothalamic C

Couples do pretty well at picking up one another's more intense feelings, like happiness or anger, but they aren't as sensitive to 'soft negative' emotions. Since spouses are each other's primary source of social support, it's important they stay attuned to each other, said psychologist Chrystyna Kouros, the study's lead aut
