    I remember CD18 by thinking you're supposed to move out when you turn 18. There's a deficiency, and the neutrophils can't "move out" into the tissues.

      helpful for non foot ball fans like few of us; I watch England foot ball so "No.18 is the referee who don't you out of the foot ball court during the game because no body can give him red card unless a LADA taxi come and give them lift! so number 18, refree BooooM, can afford LADA taxi "

    I have one for LAD that helped me remember - "LADs must be 18 to Integrate"
    LAD - Leukocyte Adhesion Deficiency
    Must be 18 - CD18
    Integrate - CD18 is an "integrin" that is necessary for migration

    A in WATER could also stand for "actin" because the WAS gene mutation leads to leukocytes/platelets being unable to reorganize their actin cytoskeleton --> ineffective APC function. Also thinking of it as Wisxott rather than Wiskott as it is X-linked recessive!

    Correct me if Im wrong, as for the CGD
    The nitro blue test
    Positive = patient have super oxide therefore patient is free from the disease
    Negative = patient has the disease as the nitroblue remains blue!
    I think you may have confused us on the positive and negative. Patient has CGD if the test is NEGATIVE not as mentioned in ur video. Do check wiki or correct me if I'm wrong

      Not quite! NBT is a colorless dye by itself. He clarifies this in the errata (pinned as the top comment). DirtyUSMLE wrote that the NBT is backwards as per the vid!
      Here's how it should be:
      Normal (positive) = turns from clear to BLUE (neutrophils can turn the dye blue because NADPH oxidase is present).
      In Chronic Granulomatous disease, it's Abnormal (Negative) = No color (indicates that there's No NADPH oxidase). No color = No NADPH Oxidase present
      Hope this helps!

    Actually, in CGD the Nitroblue tetrazolium, if it’s positive meaning it turn blue the patient doesn’t have the disease. In the other hand, if it’s negative don’t turn blue the patient will have the disease.
    So in exam if they say the test is negative it means they have the disease.

    I’m finding the pathophysiology of the infection process difficult to understand, like when does Th17 come into effect and how does it lead to Th1 or Th2? I think a lot of text books and stuff teach each part of immunology like T and B cell separate, then antibodies, then complements etc. but nothing tries to explain the whole process as a whole. I’ve gone through First Aid and General Principles Immunology section and I still don’t understand how everything is co-ordinated…
