What does'LPS-refractory' mean in regard to Bruce Beutler's research?

  • Resistant to the effects of lipopolysaccharide

  • Makes the lipopolysaccharide glow

  • Helps the body reduce fat

  • Strengthens the nervous system

Answer

Lipopolysaccharide (LPS) is a bacterial cell wall component that is toxic to human cells. In Beutler's research, LPS-refractory cells are cells that are resistant to the effects of LPS. This resistance is due to the presence of a protein called CD14, which binds to LPS and prevents it from entering the cell.
