Dimension Breakdown
DimensionScoring NotesScore
Study Design
Primarily in vitro antimicrobial, wound healing, and immunomodulatory studies, plus mouse/rat models. Some topical human studies for chronic wounds exist but injectable/systemic LL-37 has no published human RCT.
2 / 25
Sample Size
No human systemic intervention participants. Very limited topical human studies with small n.
0 / 20
Replication
In vitro antimicrobial and immunomodulatory findings very well replicated across global labs. One of the most studied human antimicrobial peptides in preclinical science.
15 / 20
Journal Impact Factor
Published in PNAS (IF ~11), Journal of Immunology (IF ~5), Journal of Biological Chemistry (IF ~5), Antimicrobial Agents and Chemotherapy (IF ~5). Strong journal placement for preclinical work.
8 / 15
Funding Independence
NIH, Swedish Research Council, and academic funded. Independent academic research with no major commercial conflicts.
7 / 10
Population Diversity
Animal/in vitro. Not applicable.
5 / 5
Researcher h-Index
Birgitta Agerberth (Karolinska) and Robert Hancock (UBC) — both h-Index 60+. Among the most prominent antimicrobial peptide researchers globally. Capped at 5.
