text: Yo, check it out, we ran some tests
  On monocyte chemotactic protein-1, no jests
  In J774 cells, we did investigate
  The impact of MCP-1, no time to wait
  
  It had an effect on nitric oxide synthase
  Inhibiting its activity, changing the phase
  When LPS and IFN-gamma induced the gas
  MCP-1 stepped in and said, "Hold up, let's pass"
  
  The inhibition was dose-dependent, for real
  Only when cells were prepped with MCP-1, the deal
  No inhibition seen when added after the fact
  MCP-1's timing mattered, that's a proven fact
  
  So, yo, listen up, here's what we found
  MCP-1 can inhibit nitric oxide's sound
  It's a regulator, controlling the synthesis
  A key player in this cellular analysis
