Anyone knows of a table with average concentration that can be found in white blood?

Something like:

  • Neutrophils - 80%
  • Mast cells - ?%
  • Dendritic cells - ?%
  • B cells - ?%
  • Helper T cells - ?%
  • Killer T cells - ?%
  • Natural killers - ?%
  • Others - (whatever is left) (the sum should be 100%, of course :))

Also: are helper T cells and killer T cells visually different? I can only find pictures of T cells, but not of each. I am also unable to find pictures of natural killers. - Thank you!

    $\begingroup$ You mean the concentration of these cells in the blood of "normal" and healthy people? $\endgroup$

  • $\begingroup$ @Luigi, I have looked up wikipedia. It does not discriminate lymphocytes nor does its source. $\endgroup$ May 13, 2015 at 11:25

Here are some figures from Cellular and Molecular Immunology, 8th Edition:

Hopefully they're helpful in some way.

  • $\begingroup$ Perfect. That's exactly what I needed - btw, do you know if (and why) it is so rare to find photos of helper T cells, killer T cells and B cells? (I can only seem to find pictures of the lymphocyte class ...) $\endgroup$ May 13, 2015 at 11:26
  • $\begingroup$ I'm a little confused as to what you mean by photos. Like bright field, scanning electron, transmission electron, etc? $\endgroup$

  • $\begingroup$ Yes, pictures of Th, Tc and B cells... I can only find picture of generic lymphocytes. (I am not a biologist!) ps: I know Th,Tc,B,etc are all lymphocytes, but I would like to have pictures of each, if those exist. Do you think they do? $\endgroup$ May 14, 2015 at 23:57
