Thymosin α1 (Tα1) and bursin-like peptide (BLP) are both immunopotentiators. In order to investigate adjuvant of thymosin α1-bursin-like peptide (Tα1-BLP), we cloned the gene of Tα1-BLP and provided evidence that the gene of Tα1-BLP in a recombinant prokaryotic expression plasmid was successfully expressed in E. coli BL21. To evaluate the immune adjuvant properties of Tα1-BLP, chickens were immunized with Tα1-BLP combined with H9N2 avian influenza whole-inactivated virus (WIV). The titers of HI antibody, antigen-specific antibodies, AIV-neutralizing antibodies, levels of Th1-type cytokines (IFN-γ) and Th2-type cytokines (IL-4) and lymphocyte proliferation responses were determined...

There is an urgent need for new treatments for chronic kidney disease (CKD). Thymosin-β4 is a peptide that reduces inflammation and fibrosis and has the potential to restore endothelial and epithelial cell injury, biological processes involved in the pathophysiology of CKD. Therefore, thymosin-β4 could be a novel therapeutic direction for CKD. Areas covered: Here, we review the current evidence on the actions of thymosin-β4 in the kidney in health and disease. Using transgenic mice, two recent studies have demonstrated that endogenous thymosin-β4 is dispensable for healthy kidneys...

Thirty percent of global mortalities are caused by cardiovascular disease, and 54% of the aforementioned amount is instigated by ischemic heart disease that triggered myocardial infarction. Myocardial infarction is due to blood flow cessation in certain coronary arteries that causes lack of oxygen (ischemia) and stimulates myocardial necrosis. One of the methods to treat myocardial infarction consists in injecting cells or active biomolecules and biomaterials into heart infarction locations. This study aimed to investigate the characteristics of a collagen⁻chitosan-based hydrogel with variations in its chitosan composition...

The mammalian dorsal root ganglia (DRG) are located on the dorsal roots of the spinal nerves and contain cell bodies of primary sensory neurons. DRG cells have been classified into subpopulations based on their size, morphology, intracellular markers, response to stimuli, and neuropeptides. To understand the connections between DRG chemical heterogeneity and cellular function, we performed optically guided, high-throughput single cell profiling using sequential matrix-assisted laser desorption/ionization mass spectrometry (MS) to detect lipids, peptides, and several proteins in individual DRG cells...

Sepsis is the dysregulated host response to an infection resulting in life-threatening organ damage. Thymosin Beta 4 is an actin binding protein that inhibits the polymerization of G-actin into F-actin and improves mortality when administered intravenously to septic rats. Thymosin Beta 4 decreases inflammatory mediators, lowers reactive oxygen species, up-regulates anti-oxidative enzymes, anti-inflammatory genes, and anti-apoptotic enzymes making it an interesting protein to study in sepsis. Areas covered: The authors summarize the current knowledge of actin and Thymosin Beta 4 as it relates to sepsis via a comprehensive literature search...

Thymosin β4 (Tβ4) is known to inhibit an inflammatory response and to increase the survival of osteoblasts on titanium (Ti) surfaces. Ti is the most widely used graft material in dentistry; however, an inflammatory response induced following implant placement results in the generation of reactive oxygen species (ROS). The oxidative stress from the production of ROS such as nitric oxide (NO) and hydrogen peroxide (H2O2) can damage surrounding cells, resulting in implant failure by decreasing cell viability...

In cystic fibrosis (CF), deletion of phenylalanine 508 (F508del) in the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel causes misfolding and premature degradation. Considering the numerous effects of the F508del mutation on the assembly and processing of CFTR protein, combination therapy with several pharmacological correctors is likely to be required to treat CF patients. Recently, it has been reported that thymosin α-1 (Tα-1) has multiple beneficial effects that could lead to a single-molecule-based therapy for CF patients with F508del...
