Knockdown of a regulatory barcode shifts macrophage polarization destination from M1 to M2 and increases pathogen burden upon <i>S. aureus</i> infection

Macrophages are driven to form distinct functional phenotypes in response to different immunological stimuli, in a process widely referred to as macrophage polarization. Transcriptional regulators that guide macrophage polarization in response to a given trigger remain largely unknown. In this study, we interrogate the programmable landscape in macrophages to find regulatory panels that determine…

Diagnosing dark sprite edges: a practical alpha compositing check

  • Verify alpha representation between image data and renderer to prevent darkened assets.
  • Compare partly transparent test image over black, white, and saturated backgrounds to isolate cause.
