Thymosin Alpha-1 vs LL-37

Thymosin Alpha-1 vs LL-37: two immune-modulating peptides. Thymosin Alpha-1 modulates adaptive immunity via T-cell regulation; LL-37 is a cathelicidin antimicrobial peptide with innate immune and wound healing effects.

Mechanism Comparison

Thymosin Alpha-1: promotes T-cell differentiation, NK cell activity, and dendritic cell maturation. Acts on adaptive immunity. LL-37: direct antimicrobial activity, promotes wound healing, modulates innate immune response via TLR signaling.

Research Applications

Thymosin Alpha-1: immune deficiency, chronic infection, cancer immunotherapy adjunct. LL-37: antimicrobial research, wound healing, inflammatory skin conditions, lung infection models.

Combination Protocol

Thymosin Alpha-1 and LL-37 target complementary immune pathways. Thymosin Alpha-1: 1.6 mg subcutaneously 2x/week. LL-37: 0.5–2 mg subcutaneously 2–3x/week or topical for wound healing.
