Thymosin Alpha 1 Mitigates Cytokine Storm in Blood Cells From Coronavirus Disease 2019 Patients

Researchers analyzed blood cells collected from individuals with COVID-19 and exposed them to Tα1 ex vivo. Gene-expression and pathway analysis showed changes in cytokine-signaling genes, CD8+ T-cell activation markers and CD38 expression, with Tα1 acting through TLR3, TLR4 and TLR9 pathways and downstream IRF3 and NF-κB signaling.
Thymosin α1 Activates Complement Receptor-Mediated Phagocytosis in Human Monocyte-Derived Macrophages
Authors: Annalucia Serafino, Fabrizio Pica, Francesca Andreola, Roberta Gaziano, Nadia Moroni, Gianluca Moroni, Manuela Zonfrillo, Pasquale Pierimarchi, Paola Sinibaldi-Vallebona, Enrico Garaci
Published: Journal of Innate Immunity, 2014; 6(1):72–88

Human monocyte-derived macrophages exposed to Tα1 in vitro showed increased uptake of beads, zymosan particles and Aspergillus niger conidia through a complement-receptor-mediated mechanism requiring microtubules and protein kinase C, while transcription of TNFα and IL-6 remained low.
Thymosin Alpha 1 Alleviates Inflammation and Prevents Infection in Patients with Severe Acute Pancreatitis Through Immune Regulation: A Systematic Review and Meta-Analysis
Authors: Ye Tian, Jie Yao, Yulong Ma, Pengfei Zhang, Xinyi Zhou, Wenlong Xie, Wei Tang
Published: Frontiers in Immunology, May 28, 2025; doi: 10.3389/fimmu.2025.1571456

This systematic review and meta-analysis pooled five randomized controlled trials (706 participants) evaluating Tα1 in severe acute pancreatitis, analyzing immune-cell ratios (CD4+, CD4+/CD8+), C-reactive protein, infection incidence and APACHE II scores across the included studies.
