The communication at the immune synapse is essential because it allows the immune cell to recognize another cell as either a normal, healthy cell or an abnormal, sick, infected cell. This then stimulates the immune cell to activate an immune response to kill the sick cell. If…

The development of high-resolution microscopy techniques and computer enhancement of previously used imaging methods to create three-dimensional images has allowed visualization and observation of immune synapses.
5. The author states, ‘virtually all the surface (cytoplasmic membrane) proteins involved in immune cells’ recognition of disease (pathogens) have been identified and named.” If this is true, then why is the immune synapse such a profound discovery?
Although the proteins involved have been identified and named, their roles and how they bring about communication between immune cells has not been entirely discovered. These discoveries, including that on the immune synapse, can be made by observing or ‘just watching’ the cells and proteins at work.
The team of Charles A. Janeway, Jr., at Yale University performed the following experiment in 1988: they fitted T cells tightly into the pores of a membrane, which was then immersed in a solution. A stimulant to activate T cells was added to the solution on only 1 side of the membrane. They then detected proteins secreted by activated T cells in the solution containing the stimulant, but the proteins were absent in the stimulant-free solution on the other side of the membrane. This experiment demonstrated the ability of immune cells to secrete proteins after activation specifically in the direction of the stimulant.
The neuronal and immune synapses are similar as they both involve communication and signal transduction between two cells through the interaction and activity of specific proteins. Neuronal and immune synapses also seem to share some common proteins, such as the Agrin protein and the Neuropilin-1 receptor. The synapse structure of both cell types forms a bull’s-eye pattern. However, they have differences too. Neuronal ...Download file to see next pagesRead More

Immune System
The immune system has many functions, however, the main one includes it acting as a natural self-defense mechanism and as a phagocytosis. Phagocytosis enables a body to save itself from threats that initiate from within a body itself. For instance, a problem in the spleen may lead to the destruction of white blood cells and platelets.

This basic unit segregates the living beings into the major categories of plants of animals. Human beings (Homo sapiens) are classified as the most developed mammals within the Kingdom Animalia. The Cell Theory This theory was proposed by Schleiden and Schwann in 1838 (The Biology Project, 2004).

Principle of Physiology
The neurotransmitter released from the terminal end of the neuron is acetylcholine which binds to nicotinic receptors on the muscle membrane. (ii) Communication across the synapse is one-way because only the presynaptic neuron releases neurotransmitter, and only the postsynaptic membrane reacts to the presence of neurotransmitter.

Growth Regulation Hormone
Growth Hormone is secreted in a pulsatile manner from the anterior pituitary gland. It is a peptide hormone consisting of 191 amino acid residues and contains 2disulphide bonds. Growth hormone secretion is regulated by hormones like GHRH , Somatostatins and Somatomedins which either stimulates GH or inhibits GH release by positive and negative feedback effects respectively.Conditions like hyprglycemia and prolonged sleep increases GH secretion levels.

The human immune system
This is repeated in all categories as dictated by the time factor of 6, 12, 18, and 24 months. The relevance and inclusion criterion for this arrangement is due to the fact that data is presented randomly and does not match particular test subjects. Therefore, rearranging the data to follow a numerical chronology makes it easy for analyzing with regards to values and figures.
