Exogenous antigen is taken inside and degraded
-MHC complex goes through golgi complex.
Class 2 mhc molecules transported to cell surface.
Class 2 mhc binds invariant chain to block binding of endogenous antigen.
Invariant chain is degraded, leaving clip fragment.
Clip fragment is exchanged for angigenic peptide.
Class 2 mhc, peptide complex binds to cd+4 cells.

Handout IG2-2 Class I MHC-Peptide Interactions Place the steps of the antigen-processing pathway for endogenous antigen in the correct order Alpha chain of class I MHC binds peptide. Endogenous antigen within cytosol is degraded by proteasome. Peptides are transported into endoplasmic reticulum by TAP Alpha chain of class I MHC binds β2-microglobulin. Peptide-class I MHC is transported to Golgj complex and then to cell surface. Class I MHC peptide binds to CD8+T cell.
Another exaumple of haptens body to Per response occurs wi The best known example of Handout IG2-1 Categorization Categorize the characteristics in the following list with the appropr complex (MHC) class Expressed on all nucleated cells .Peptide-binding cleft is closed at both ends Presents endogenous antigen to CD8+ T cells . Has one alpha chain and beta:-microglobulin . Peptide-binding site holds peptides between 8 and 11 amimacrophages cells, and thymic epithelium) ting cells (B lymphocytes, monocytes, macrophages, dendritic . Has...
The transporter in antigen processing genes encode subunits of a heterodimer pump that transports peptides from the cytosol into the endoplasmic reticulum, where they can associate with newly translated Class la chains O B-2 microglobulin. Proteosomes. Immunoglobulin molecules. Class Il a and B chains. Question 20 5 pts Soluble proteins are examples of: Bone marrow dependent antigens. Bone marrow independent antigens., Thymus dependent antigens. Thymus independent antigens. Good food. The features of bound peptide fragments isolated from different class molecules...
Could you help with any of these ? and provide an explanation
so I'll understand? thank you so much
Circle all that apply 1) A patient has inherited two defective genes for TAP2 (remember the case study from before) Which of the following are true? (circle all that apply): - The patient will have a scarcity of CD4+ T helper cells -MHC class I molecules will not be expressed to any extent on the patient's cells -MHC class II molecules...

5-1 T cells recognize antigen when the antigen a. forms a complex with membrane-bound MHC molecules on another host-derived cell b. is internalized by T cells via phagocytosis and subsequently binds to T-cell receptors in the endoplasmic reticulum c. is presented on the surface of a B cell on membrane-bound immunoglobulins d. forms a complex with membrane-bound MHC molecules on the T cell e. bears epitopes derived from proteins, carbohydrates, and lipids. 5-2 a....
