Immunological Recognition
T-Cell receptor (TCR) is the key mediator in adaptive cell mediated immune response. A complex molecular mechanism, many processes of which aren’t yet fully known, underlies the intrinsic ability of TCRs to recognize a broad range of their target molecules. These target molecules or binding partners of TCRs are universally linear antigenic peptides which bind to major histocompatibility complex molecules (p-MHC).

Immune Cell Structures
The apparent randomness in our immune systems is mainly a result of genetic and environmental complexity. Beside this intrinsic randomness, however, the changes in the immune cell’s morphology and the localization of the molecules involved in immunity, when an organism senses a pathogen (virus, bacteria,…), usually cause well-defined patterns.
Mitochondrial Structure
Mitochondria are dynamic and versatile organelles with two main well-known tasks of providing energy (ATP) and Calcium (Ca2+) buffering. These essential components can be considered as movable tuners of signaling events that the cell can deploy when they are most needed. In many cell types, what facilitates their movement is a constant process of fission and fusion. A balance between fission and fusion controls not only the overall mitochondrial morphology but also its size and number.
