What this research studies
This lab project studies macrophages, a type of immune cell that uses 'cell drinking' (macropinocytosis) to clear debris, present antigens, and help resolve inflammation. Researchers will use CRISPR gene editing and live-cell imaging to change levels of the proteins SHP1 and SYK and watch how the cells' internal scaffolding (actin) and signaling lipids behave. Experiments will compare resting and activated macrophages and use image-based measurements to see how these changes affect macropinocytosis. The goal is to map the cellular steps that control this cleanup process and how immune receptors influence it.
Who could benefit from this research
Good fit: People with autoimmune or inflammatory conditions who are interested in contributing to research or being considered for future trials related to anti-inflammatory strategies would be the most relevant group.
Not a fit: Patients seeking immediate treatment or those without autoimmune or inflammatory conditions are unlikely to get direct benefit from this basic laboratory research.
Why it matters
Potential benefit: If successful, this work could point to new molecular targets to better control inflammation in autoimmune diseases and guide future therapies.
How similar studies have performed: Preliminary CRISPR screens in the investigator's lab highlighted SHP1 and SYK, but combining CRISPR with live imaging to map their roles in macropinocytosis is relatively new.
