Comparison
While LL-37 acts as a broad-spectrum antimicrobial and immunomodulatory peptide involved in host defense and wound repair, but can also promote inflammation and cancer cell proliferation in some contexts5215, Tesamorelin is FDA-approved to reduce excess visceral adipose tissue in HIV-associated lipodystrophy and is studied for broader body-composition, NAFLD, and cognitive effects via GH/IGF-1 axis modulation1893.
While LL-37 works as a cationic amphipathic 37-amino-acid cathelicidin peptide generated from hCAP18 that disrupts microbial membranes and modulates innate immunity, including chemotaxis, cytokine induction, and NET formation521586, Tesamorelin is a full-length 44-amino-acid GHRH analog with an N-terminal trans-3-hexenoic acid modification that binds GHRHR, activating cAMP/PKA signaling to increase endogenous GH and IGF-1, with improved stability versus native GHRH182893102.
LL-37 is 37 amino acids long, whereas Tesamorelin is longer as it has a length of 44 amino acids. LL-37 is made up of a sequence of Leucine, Leucine, Glycine, Aspartic acid, Phenylalanine, Phenylalanine, Arginine, Lysine, Serine, Lysine, Glutamic acid, Lysine, Isoleucine, Glycine, Lysine, Glutamic acid, Phenylalanine, Lysine, Arginine, Isoleucine, Valine, Glutamine, Arginine, Isoleucine, Lysine, Aspartic acid, Phenylalanine, Leucine, Arginine, Asparagine, Leucine, Valine, Proline, Arginine, Threonine, Glutamic acid, Serine. Tesamorelin is made up of a sequence of Tyrosine, Alanine, Aspartic acid, Alanine, Isoleucine, Phenylalanine, Threonine, Asparagine, Serine, Tyrosine, Arginine, Lysine, Valine, Leucine, Glycine, Glutamine, Leucine, Serine, Alanine, Arginine, Lysine, Leucine, Leucine, Glutamine, Aspartic acid, Isoleucine, Methionine, Serine, Arginine, Glutamine, Glutamine, Glycine, Glutamic acid, Serine, Asparagine, Glutamine, Glutamic acid, Arginine, Glycine, Alanine, Arginine, Alanine, Arginine, Leucine.
