Quick answer
What is Thymosin alpha 1?
Built from index records dated 2026-10-09 to 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk. No qualified clinical reviewer. How this site works
Thymosin alpha 1 is a peptide, grouped on this site under Endocrine and immune signalling peptides, and the 12 research records kept here are 2 from studies in rats or mice, 4 from trials in people and 6 that do not state what kind of study it is.
The literature search returned 746 records. This site keeps 12 of them, which is 1.6 per cent of what came back.
What it is
This site puts it in the Endocrine and immune signalling peptides group.
Reported in the retrieved records to act on immune cell populations, including activation of dendritic cells, rather than at a single named receptor.[1]
Stated in the title of the cited 2004 Blood paper.
What kind of records
Several of the records kept here are trials in people.
That sentence is produced by counting, not by reading. What was counted: 4 of 12 indexed records are interventional human trials by their own assigned publication type.
What this does not settle
- What it does in a body. Counting records is not reading them, and nothing here has been read in full.
- Whether it causes harm. No adverse-effect row was taken from any source for this entry.
- How long it lasts. No pharmacokinetics source was retrieved for this entry.
- What the other 734 retrieved records say. They are not in this index.
The longer explanation
Where this comes from
The records cited above, in full.
