re-uptake
LowTechnical/Specialized
Definition
Meaning
The process by which a cell, especially a neuron, reabsorbs and reclaims a neurotransmitter it has previously released.
More generally, the process of taking something back up or reabsorbing it after it has been released or transported elsewhere.
Linguistics
Semantic Notes
Primarily a noun. Most often used in neuroscience, pharmacology, and psychology. The hyphen is standard but the unhyphenated form 'reuptake' is also common.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or semantic differences. Spelling with hyphen is equally standard in both varieties. Unhyphenated form 'reuptake' is slightly more frequent in American scientific writing.
Connotations
Identical technical connotations in both varieties.
Frequency
Frequency is very low in general corpora for both, but slightly higher in American English due to greater public discussion of medications (SSRIs) that affect it.

Virtually never used.
Academic
Exclusively used in neuroscience, pharmacology, psychology, and biochemistry papers.

Examples
By Part of Speech
verb
British English
- The transporter protein helps to reuptake serotonin from the synaptic cleft.
- These neurons efficiently reuptake dopamine.
American English
- The medication prevents neurons from reuptaking serotonin as quickly.
- The mechanism responsible for reuptaking glutamate is complex.
adverb
British English
- [No standard adverbial use]
American English
- [No standard adverbial use]
adjective
British English
- The re-uptake process is energy-dependent.
- They studied the re-uptake inhibitor's effects.
American English
- The reuptake mechanism is a key therapeutic target.
- Serotonin reuptake inhibitors are commonly prescribed.
Examples
By CEFR Level
- This word is not typically used at A2 level.
- Some medicines work by slowing the re-uptake of a brain chemical called serotonin.
- The drug's primary action is to inhibit the re-uptake of norepinephrine, leaving more of it available in the brain.
- Advances in neuroimaging allow researchers to visualize the density of dopamine re-uptake transporters in the living brain.
Learning
Memory Aids
Mnemonic
Think: RE- (again) + UPTAKE (taking up). A neuron sends a message (releases a chemical), then takes it UP again – RE-UPTAKE.
Conceptual Metaphor
NEUROTRANSMISSION IS A POSTAL SYSTEM: Release is sending a letter; re-uptake is the postman retrieving the envelope for reuse.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'пере-взятие'. The standard translation is 'обратный захват'.
- Do not confuse with 'реабсорбция' (reabsorption), which is a broader biological term; 'обратный захват' is specific to neurotransmitters.
Common Mistakes
- Misspelling as 'reuptake' without the hyphen (though this is increasingly accepted).
- Using it as a verb ('to re-uptake'); the verb form is 'reuptake' (less common) or 'be reabsorbed'.
- Confusing it with 'reabsorption' in non-neural contexts.

FAQ
Frequently Asked Questions
Yes, the unhyphenated form is very common, especially in American English and in compound terms like 'reuptake inhibitor'. Both forms are accepted.
The verb form 'reuptake' (one word, no hyphen) exists but is less common than the noun. It's more typical to use phrases like 'undergo re-uptake' or 'is reabsorbed'.
'Re-uptake' is a specific type of reabsorption, referring almost exclusively to the cellular retrieval of neurotransmitters from a synapse. 'Reabsorption' is a broader biological term for taking back substances (e.g., water in the kidneys).
Many psychiatric and neurological medications (like antidepressants for depression or stimulants for ADHD) work by blocking the re-uptake of specific neurotransmitters, thereby increasing their activity in the brain.
