A 2025 proof-of-concept study published in Brain, Behavior & Immunity – Health explored exactly that question — using a thymus-derived immune peptide called thymosin alpha-1 (Tα1, thymalfasin) in patients with Common Variable Immunodeficiency (CVID) who also had depression .

Antimicrobial peptides (AMPs) are short chains of amino acids that form part of the innate immune defence system across humans, animals, plants, and microorganisms. Unlike conventional antibiotics, AMPs act rapidly and through multiple mechanisms, making them a promising area of research in the global response to antimicrobial resistance. AMPs exhibit activity against a broad range of pathogens, including bacteria, fungi, viruses, and parasites, while also playing roles in immune modulation and inflammation control. 🔬 What Are Antimicrobial Peptides? AMPs are typically: Short peptides (5–50 amino acids) Positively charged, allowing interaction...
