  • MALT may consist of a collection of lymphoid cells, or it may include small solitary lymph nodes. (medscape.com)
  • The roles of the M cells include absorption, transport, processing, and presentation of antigens to subepithelial lymphoid cells. (medscape.com)
  • It's a monkey virus coming out of a monkey cell line and that's the problem, but the spike protein is clearly [causing] the disease. (fromthetrenchesworldreport.com)
  • It produces a version that has a couple of prolines in it, side by side at the critical place where this spike protein normally would fuse with the cell that it's infecting. (fromthetrenchesworldreport.com)
  • However, both the mRNA and the protein it produces have been changed from the original version in the virus with the intent to increase rate of production of the protein in an infected cell and the durability of both the mRNA and the spike protein it codes for. (theepochtimes.com)
  • IL-17 has pleiotropic activities, including induction of TNF-α, IL-1β, IL-6, IL-8, G-CSF, and monocyte chemoattractant protein-1 on various types of cells ( 8 ). (aai.org)
  • The particles basically get your cells to produce lots and lots of spike protein in a hurry. (leadstories.com)
