When a cell does deviate from the norm, it may signal a malfunction: Skewed cell size is a hallmark of some diseases. Take small-cell carcinoma, a type of cancer that usually sprouts in the lungs, in which tumor cells are so puny that they barely have room for any cytoplasm.MITCH ...
Some vegetable sources contain quite a bit of protein. Nuts, beans and soybeans are all high in protein. By combining them, you can get complete coverage of all essential amino acids. The digestive system breaks all proteins down into their amino acids so that they can enter the bloodstream...

This chapter will focus on cell signaling and signal transduction, that is, the extremely complex series of reactions by which cells receive and react to external signals (for reviews, see Hunter...doi:10.1007/978-3-642-55539-8_4Edmond H. Fischer...
How are proteins made and what do they do? The Proteome: The proteome is the full complement of proteins in a given type of cell or tissue under specific conditions. The proteome, unlike the genome, is dynamic, responsive to environmental conditions and cues from other cells, and expansive ...
What Does DNA Do? Where Do We Get Our DNA? Deoxyribonucleic acid, or DNA, is a molecule containing instructions on how to make a living organism. Its structure and sequence instruct the cell on how to make proteins, which go on to carry out important functions of a cell. Many cells for...
First, develop a balanced diet. As we know, the core of improving immunity is to enhance immune cells and immune molecules. Both two have a common feature. There is a high demand for proteins. And the source of the ...

Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
