Splenopentin

A spleen-derived immunomodulatory pentapeptide studied mainly in 1980s and 1990s European immunology research.

Overview

Splenopentin is an immunomodulatory pentapeptide originally derived from a bovine spleen factor, studied mainly in the 1980s and 1990s, particularly in European immunology research. Interest centered on its ability to promote T-cell maturation and to restore immune responses in models of immunodeficiency. The modern literature is sparse.

Mechanism

Splenopentin is described as an early signal for T-lymphocyte differentiation, acting on immature thymocytes to induce maturation markers and functional responsiveness. Its molecular target and receptor are not clearly defined.

Expected Effects

  • Improved T-cell maturation markers in experimental models
  • Restoration of immune function in experimentally immunocompromised animals
  • Historically proposed as an immune-restorative agent, with limited subsequent follow-up

Side Effects & Tolerability

Published tolerability data are minimal and dated, and no contemporary safety assessment is available. The peptide is best regarded as a historical research tool.

Storage

Store lyophilized peptide cold and desiccated, protected from light and moisture, per the supplier certificate of analysis.
