Albinism: type I vs. II classification :

“One has None.Two Accumulates”

Type I: have no pigment.
Type II: No pigment at birth, but accumulates as person ages

Histamine: features

HISTAMINE:

HCL production
Inflammation
Strong vasodilator
Therapeutic vaue none
Allergy
Mast cells
Neurotransmitter/ Narrow airways
IgE

Immunoglobulins and order B cells present them

MADGE (character from the old dishwashing liquid commercial):

IgM
IgA
IgD
IgG
IgE
  *Order of presentation by B cells (which is made first, IgD or IgM?) B cells present IgM primarily, and then IgD.Just remember why all of us are going through this pain…to become M.D’s. For a B cell to be competent, it must get its MD.

  *Finally, by the same rule, B cells must first release M then G immunoglobulin on primary exposure.

MHC: loci creating class I vs. II

Class 1 has 1 letter:

HLA I is HLA-A, HLA-B, HLA-C.

Class 2 has 2 letters:

HLA II is HLA-DP, HLA-DQ, HLA-DR.

MHC I vs. MHC II: properties

“Immunity helps to exterminate fun for bacteria”

MHC I vs. II: T cell interaction

The “=8” equation:

2×4=8, and 1×8=8.

MHC II goes with CD4.

MHC I goes with CD8.

T and B cells: types

When bacteria enter body, T-cell says to B: “Help Me, Catch Some!” B-cell replies: “My Pleasure!”:

*T-cell types:

Helper

Memory

Cytotoxic

Suppressor

  *B-cell types:

Memory cell

Plasma cell
