neurotropism
Học thuậtThân thiện
Definition
- Noun:
- An affinity for neural tissues: A specific attraction or tendency to grow toward, affect, or infect nerve cells or nervous system tissue.
Usage
- The term "neurotropism" is a specialized scientific and medical term. It is primarily used to describe the behavior of certain viruses (e.g., rabies virus, herpes simplex virus, poliovirus) or toxins that show a specific preference for infecting or damaging neurons.
- It can also be applied in neuroscience and developmental biology to describe the guided growth of nerve axons toward specific targets.
Examples
- The neurotropism of the rabies virus explains why it causes such severe neurological symptoms.
- Researchers are studying the virus's neurotropism to understand how it enters the central nervous system.
- The neurotropism of this chemical makes it a potent neurotoxin.
Advanced Usage
- Adjectival Form: The concept is most commonly used in its adjectival form, neurotropic.
- Example: "Herpes simplex is a neurotropic virus that establishes latent infections in sensory ganglia."
- Specificity: The term implies a selective affinity. A substance with general toxicity that also damages nerves is not specifically neurotropic; neurotropism indicates a action on neural tissue.
Variants and Related Words
- Neurotropic (adjective): Having an affinity for or growing toward neural tissue.
- Example: "The study focused on neurotropic factors that guide neuron development."
- Neurotropism is related to, but distinct from, neurotrophism (the promotion of nerve growth and survival, often via neurotrophic factors).
Synonyms
- Neural affinity
- Neural tropism (a more general term where the target tissue is specified)
- Selectivity for nervous tissue
Antonyms
- Non-neurotropic: Lacking affinity for neural tissues.
- Pantropic: Having an affinity for many or all types of tissues (opposite of selective tropism).
Noun
- an affinity for neural tissues
