What is an anticalin?
An anticalin is any of a class of artificial proteins which are able to bind to antigens.
What does N1H1 stand for?
Hemagglutanin & Neurominadase are surface antigens. The number '1' refers to the specific sub-type of those antigens. The sub-types differ in their basic structure.
What is the difference between a class I MHC mechanism vs a class II MHC mechanism?
The Class I MHC molecules process endogenous(intracellular) peptides/antigens whereas the Class II process exogenous(extracellular) peptides/antigens. The Class I molecules are assembled and located in the ER whereas the Class II are assembled in the ER but located in the endosomes. When extracellular peptides are taken into the cell via receptor mediated endocytosis or phagocytosis, they will be transported into the endosomes and get degraded. This will enable the peptide generated to be loaded onto the Class II molecules. For Class I, when a bacteria or virus infect a cell, they will replicate and produce proteins. These proteins will be ubiquitinated and degraded by the proteasome. This smaller peptides can then be transported into the ER via the TAP transporters, that are complexed with the Class I molecules, to be loaded onto the Class I molecules.
What class of macromolecule would antibodies belong?
Antibodies belong to the class of macromolecules known as proteins. They are Y-shaped proteins produced by the immune system in response to the presence of foreign substances called antigens.
What role does the macrophage play in?
presents antigens of an engulfed pathogen in its class II MHC molecules to helper T cells, and releases IL-1
What causes plasma cells to produce antibodies?
Yes. Blood plasma is blood serum with the fibrinogens. Serum includes all proteins not used in blood clotting (coagulation) and all the electrolytes, antibodies, antigens, hormones, and any exogenous substances (e.g., drugs and microorganisms).
Where are Class II molecules found?
Presented by APCs as MHC-exogenous peptide complex
What are 'first class proteins'?
animal proteins are called first class proteins.
What is the differant between first class and second class?
proteins from animal origin are called first class proteins. meat and fish are first class proteins because they contain all the essential amino acids (which cannot be made by the body), plant proteins are called second class proteins.
What is the duration of Oprah Presents Master Class?
The duration of Oprah Presents Master Class is 3600.0 seconds.
What the different of first class and second class of protein?
proteins from animal origin are called first class proteins. meat and fish are first class proteins because they contain all the essential amino acids (which cannot be made by the body), plant proteins are called second class proteins.
A hormone is an example of which functional class of proteins?
A hormone is an example of the globular class of proteins
