Secretory leukocyte protease inhibitor (SLPI) is a small but powerful member of the serine protease inhibitor family, which includes proteins such as elafin and alpha1 anti-trypsin. These proteins all have similar structure and antiprotease abilities, but SLPI has been found to have an additional role as an anti-inflammatory factor. It can inhibit the production of pro-inflammatory cytokines in cells stimulated with lipopolysaccharide, prevent neutrophil infiltration in murine models of lung and liver injury, and regulate the activity of the transcription factor NF-κB. In this review, we will revisit SLPI’s unique biochemistry, and then explore how its anti-inflammatory functions can be linked to more recent findings showing that SLPI can localize to the nuclei of cells, bind DNA, and act as a regulator of gene expression.
Difficult news has been described as any news that adversely and seriously affects an individual's view of their future. Research in oncology genetic counseling demonstrated that individuals do not prefer in‐person or telephone delivery of their genetic test results. However, in the prenatal setting, there is limited research examining how patients prefer news related to their pregnancies be disclosed. This study aimed to assess the experiences and preferences of prenatal patients who received difficult news by telephone. A semi‐structured interview guide was developed to assess patients' personal definitions of difficult news and their experiences receiving the news by telephone. Fifteen patients seen prenatally by a genetic counselor were interviewed. Interviews were transcribed and consensus‐coded, using inductive content analysis to identify several themes. The most common definition of difficult news included unexpected, life‐changing, or devastating information. Participants described aspects of their experience and strategies employed by their genetic counselor that was helpful when receiving the news, which was found to align with the SPIKES protocol, a six‐step process of delivering difficult news to patients. Additional techniques that participants identified as beneficial and satisfactory included the genetic counselor's use of empathy, non‐directiveness, and continuity and coordination of care. Participants also provided recommendations for improvement, including a discussion of the mode of result disclosure during pretest counseling, an option to follow up with their genetic counselor, personalized resources, and a summary of the results call. The findings of this study demonstrate that a patient‐centered approach is preferred by patients who receive difficult news by telephone in the prenatal setting. Patients' identification of beneficial communication techniques and suggestions for improvement can be implemented by any healthcare provider responsible for delivering difficult news to prenatal patients.
Myelin‐associated glycoprotein (MAG) and Nogo inhibit neurite outgrowth by binding to receptors such as NgR1, PirB and LRP1, and they have also been shown to induce phosphorylation of Smad2, a key intermediate in the transforming growth factor β (TGFβ) signalling pathway. In this study, we determined that MAG and Nogo do not transactivate the TGFβ receptor through their canonical receptors or discoidin domain receptor 1, which we identified as a novel receptor for MAG and Nogo. Instead, MAG and Nogo promoted Smad2 phosphorylation by stimulating secretion of TGFβ. Proteomic analysis of the neuronal secretome revealed that MAG also regulated the secretion of proteins that affect central nervous system plasticity—inducing the secretion of S100A6, septin‐7 and neurofascin 186, while inhibiting the secretion of frataxin, MAP6, syntenin‐1 and GAP‐43. This represents a novel function for MAG that has broad implications for the treatment for spinal cord injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
