Chart 26-9 · 12 min
Self and not-self
A read of this page, with the plate.


The passport. MHC 1 on cells that belong. Infected cells wear a second marker; CD-8 matches it. MHC 2 on defenders who show fragments. Self is safe. Not-self is attacked — an infected cell, a transplant, a house the map failed to protect. Autoimmunity as the map attacking the house — a physician. Occupancy is Chart 1-1 as a neighbor, not the whole teaching of not-self.
Her voice, from the class.
Self and not-self — MHC1, MHC2, antigen presenting
Practice
Ask self, not-self, presenting. If the house is attacking the house, you stop.
Check
MHC 1 on 26-9 lives:
- Only on B-cells
- On all cells that are OK — self is safe ✓
- Only in the thymus
The passport.
MHC 2 on 26-9 lives:
- On every cell
- On defender cells that show fragments ✓
- On IgE
Presenting.
Not-self on this hour is:
- Only Chart 1-1
- An infected cell wearing antigen, a transplant, a house the map failed — occupancy is a neighbor, not the whole teaching ✓
- A dose of zinc
Real teaching.
Autoimmunity on this hour is:
- Histidine you dose
- A physician — self attacked ✓
- An overlay you yank
Then you leave.
Zinc on the passport hour:
- Class 5 OA
- Not this hour’s card — Bio-Thymus belongs here ✓
- A dose of a joint
Own material.
CD-8 matches:
- MHC 2 only
- The invader’s antigen next to MHC 1 on an infected cell ✓
- IgA
Attack.
Transplant on this hour:
- A student kit
- A physician — a passport that is not this house ✓
- Chart 1-1 as the whole teaching
Not-self.
Self is safe means:
- You prescribe MHC
- MHC 1 on cells that belong ✓
- Overlays
That's the work.
Irregular surface on MHC 2:
- A dose you write
- More room to show fragments ✓
- A hunt
That's the work.
If the house is attacking the house:
- You prescribe Bio-Thymus
- You stop — autoimmunity belongs with a physician ✓
- You hunt occupancy
The stop.
