Out now @nature.com! We report a new means of cell communication: receptor-free signal transduction. TLRs engage MyD88 for minutes, yet myddosomes signal for hours. TRAM releases myddosomes from TLRs, letting them mature and sustain signaling in the cytosol. rdcu.be/jGdKxErXyAsa Details below:

Congrats to Samira Schiefer on her new paper in Science Advances! We analysed 70 natural human IFNB1 variants & found both loss- & gain-of-function IFNβ proteins, revealing unexpected diversity in antiviral immunity. Great effort with Dave Jones & Florence Kwaschik! www.science.org/doi/10.1126/...

Graphing and statistically analyzing data is challenging without coding expertise. This Community Page by @avishenoy.bsky.social introduces grafify online, a free, browser app for generating publication-quality graphs and performing statistical tests and comparisons. 🧪 #AcademicSky plos.io/3RpUg6E
Types of graphs and color schemes available in grafify online.
A. Examples of graphs that can be plotted with grafify online. Box and whiskers and violin plots show a line at the median with a box representing the interquartile range (IQR) and whiskers that show 1.5× IQR. Bar graphs and point and error-bar plots show the mean, and the dispersion can be shown as standard deviation (default), standard error of mean, or 95% confidence intervals. Before–after plots show matched data. Numeric XY graphs have numeric variables on both and X- and Y-axes and require a grouping variable that is either categorical (Numeric XY 1) or numeric (Numeric XY 2). B. Categorical (left) and numeric (right) color palettes that are accessible to colorblind individuals

Europe's MSCA postdoctoral fellowships are now attracting many researchers who would have gone to the US. So the payline has dropped below 10% (~1,600 fellowships to 17k applicants). Super tough situation. One more reason to double the next Horizon budget, as proposed by the EU Commission.

We report today that the structurally complex PAMP LPS can be broken down to a simple pattern that is detected by the innate immune receptor caspase-11. This pattern is a lipid containing a negative charged headgroup + acyl chain ≥14 carbons. www.science.org/doi/10.1126/...

LPS binding caspase activation and recruitment domains (CARDs) are bipartite lipid binding modules
A bacterial sensory protein detects self- and nonself-lipids by similar mechanisms.
