What belongs here

Neuron-support proteins delivered by any route: injection, pump, cells or gene.

What does not belong here, however close it looks

Measuring these proteins in blood without delivering them is biomarker work.

What has been looked at

Counted from what the sources catalogue, not from reading the work. It says how much exists and over what span of years — never what any of it found.

  • Registered or indexed as work in people: 446 records · 1976–2026
  • Indexed as work in animals: 947 records · 1975–2026
  • Indexed as laboratory work: 116 records · 1981–2026
  • The source has not said who or what was studied: 221 records · 1997–2026
  • No matching published catalogue records are linked above. Human-review status must be checked on the evidence itself.

Found in the scientific sources, not yet checked

Titles and identifiers as the sources publish them. Nobody here has read these papers, and nothing on this shelf is a result, a recommendation or evidence that anything works. Each line opens the original.

1730 records

This grouping is the source's own cataloguing, not a reading of the paper. It says where a record was filed, not what it found.

Where this was looked for, and when

The latest collection walk and the accumulated shelf have different scopes. A zero applies only to that source query and its date window; older records may remain on the shelf. It does not mean no research exists.
