CHEMOATTRACTIVE SIGNAL Meaning and
Definition
-
A chemoattractive signal refers to a biochemical or molecular cue that influences the directional movement of cells, organisms, or particles towards a specific location or target. This signal acts as an attractant, guiding the movement of cells or organisms along a concentration gradient of the particular molecular cue.
Chemoattractive signals are commonly observed in various biological processes, including development, immune responses, and neural guidance. During development, chemoattractive signals enable cells to migrate and differentiate to their appropriate destinations within tissues and organs. In immune responses, they help in the recruitment of immune cells to the site of infection or injury. In neural guidance, chemoattractive signals assist in the navigation of growing neuronal projections towards their correct target, enabling the establishment of functional neural circuits.
These signals are often generated by specialized cells or tissues and are perceived by specific receptors on the surface of the responding cells or organisms. Examples of chemoattractive signals include chemokines, growth factors, hormones, and various signaling molecules. They can be secreted by cells in the vicinity of the target location or released in distant locations to attract migrating cells or organisms over long distances.
Understanding the mechanisms and the roles of chemoattractive signals is crucial in various fields, including cell biology, developmental biology, immunology, and neuroscience, as it provides insights into the complex processes involved in cell migration, tissue formation, and organ development.

Etymology of CHEMOATTRACTIVE SIGNAL
The word "chemoattractive signal" combines the roots "chemo-" and "attractive" with the term "signal". Here is the breakdown of its etymology:
1. Chemo-: The prefix "chemo-" derives from the Greek word "kheîma" meaning "to pour", which evolved in modern Greek to "khymos" meaning "juice" or "juice of plants" in reference to their taste. In scientific contexts, "chemo-" refers to chemicals or chemical reactions.
2. Attractive: The word "attractive" originates from the Latin verb "attrahere", which combines "ad" meaning "to" and "trahere" meaning "to draw" or "pull". It signifies the ability to draw or allure something toward oneself.
