A large-scale method for the isolation of thymosin beta 4 (up to 120 mg) and thymosin beta 9 (up to 40 mg) from bovine lung (up to 2 kg) was developed. The isolation protocol included tissue homogenization in 0.4 M HClO4, centrifugation, solid-phase extraction through LiChroprep RP-18 material, chromatofocusing on polybuffer exchanger PBE 94-modified Sepharose and dialysis against water. The isolated products were characterized by analytical isoelectric focusing, reversed-phase HPLC, electrospray ionization mass spectrometry and amino acid analysis. The method developed is rapid and convenient, requires no expensive equipment and can be used for the isolation of thymosin beta 4 and homologous peptides from various animal tissues.

Dry eye disease (DED) is a prevalent inflammatory condition significantly impacting quality of life, yet lacks effective pharmacological therapies. Herein, we proposed a novel approach to modulate the inflammation through metabolic remodeling, thus promoting dry eye recovery. Our study demonstrated that co-treatment with mesenchymal stem cells (MSCs) and thymosin beta-4 (Tβ4) yielded the best therapeutic outcome against dry eye, surpassing monotherapy outcomes.

Autologous fat grafting is a widely used technique in plastic and reconstructive surgery, but its efficacy is often limited by the poor survival rate of transplanted adipose tissue. This study aims to enhance the survival of fat grafts by investigating the role of thymosin beta-4 (Tβ4) in facilitating mitochondrial transfer from adipose-derived stem cells (ADSCs) to adipocytes and newly formed blood vessels within the grafts via tunneling nanotubes (TNTs). We demonstrate that Tβ4 upregulates the Rac/F-actin pathway, leading to an increased formation of TNTs and subsequent transfer of mitochondria from ADSCs.

Diethylene glycol dimethacrylate (DEG)-crosslinked polystyrene (PS) resin offers a promising alternative to traditional divinyl benzene (DVB)-PS resin for solid-phase peptide synthesis (SPPS), particularly for challenging sequences with hydrophobic or bulky amino acids. DEG-PS resin's reduced hydrophobicity and enhanced flexibility improve synthesis efficiency, yielding peptides up to 28 residues with higher purities and yields compared to DVB-PS. In various syntheses, DEG-PS outperformed DVB-PS resin, with higher purities and yields for challenging peptides such as ABC analogue (73.

Objectives: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, and fibrotic interstitial lung disease. The two drugs indicated for IPF have limited efficacy and there is an urgent need to develop new drugs. Thymosin β4 (Tβ4) is a natural endogenous repair factor whose antifibrotic effects have been reported.
