Neuroprotective effects of peptides bioregulators in people of various age
R. S. Umnov, N. S. Linkova, V. Kh. Khavinson · Adv Gerontol. 26(4):671–678. PMID 24738258
A gateway review comparing polypeptide complexes (Cortexin and Cerebrolysin) with short peptides (Semax, Cortagen and Pinealon). It discusses older populations and cellular mechanisms; the abstract supplies no trial-quality assessment.
- Population / setting
- Review of earlier research
- What was checked
- Indexed English abstract checked; Russian full text not retrieved.
Limitations & review scope
- Source-linked does not mean a completed risk-of-bias review.
- A review is not an independent clinical replication; proposed mechanisms do not establish efficacy or safety.
