The processing requirements include successful completion of: 1  The application process, which includes a background and polygraph examination, a medical examination, a physical fitness evaluation, and a written examination; 2  24-26 weeks of intensive Academy training.
The cell membrane, being exposed to the outside environment, is an important site of cell-cell communication. As such, a large variety of protein receptors and identification proteins, such as antigens, are present on the surface of the membrane.
â¢ Antigen is recognized in conjunction with proteins of the major histocompatibility complex (MHC). â¢ Different antigen degradation and processing pathways produce MHC-peptide complexes where endogenous peptides associate with class I molecules and exogenous peptides associate with class II molecules.2) Present an overview of differential processing of antigens in the MHC class I and class II pathways. (3) Discuss MHC restriction as related to presentation of antigens. (4) Present an overview of disease association with MHC type. (5) Introduce CD1 non-peptide lipid presentation.
