It is a well known fact that the organisms constantly interpret signals and receive them from the environment; it is possible for signals to arrive in various forms such as sound, touch, water, heat and light. Signals from other cells are received by cells of multi-cellular organisms and this includes the signals for differentiation and division of cells. It is important for most of the cells within our bodies to be in constant receiving of signals that not only keep them functioning but also keep them very much alive.
It is also found that the organisms have signalling systems that notify about the presence of the pathogens, which further leads to a response that is highly protective in nature. There are many key concepts relating to this; these point towards the fact that a lot of signalling systems in biology actually have steps that are either similar or related. It is possible that the same signalling system can result into different responses in various cells and diverse organisms.
Cells make use of a huge number of signalling pathways that help in regulation of their activity; on Mechanisms are further responsible for transmission of information to cell. Neuronal signalling is yet another interesting chapter that relates with the central nervous system connected with each other so that neural circuits can be formed.
Study of mechanisms in cell signalling is an interesting thing to know about; it is this study that is resulting into the new understanding of various diseases. It also opens up the doors for new strategies for various therapies that you only wondered about, so far. Cell signalling can be well explained with its biological context; there has been quite a good deal of explosion signalling pathways and components characterization. Cell signalling is also laying foundation for various competitive industries that can generate hardcore business and money from it.
