An immunomodulatory peptide derived from the thymus gland, approved in several countries for hepatitis B/C and studied for immune enhancement in cancer and infectious diseases.
To determine the effect of thymosin α1 (Tα1) on the phenotypic and functional maturation of HL‑60 cells, freeze‑thaw antigen‑loaded dendritic cells (DCs) were derived from peripheral blood mononuclear cells (PBMCs) of children with acute lymphoblasti…
Thymosin α1 (Tα1) has been tested for cancer therapy for several years, in most cases, the anti-tumor effect of Tα1 was limited, especially when Tα1 was used as a single agent. The role of Tα1 in cancer treatment and the regulatory mechanisms by whic…
Thymosin α1 (Tα1), an epithelial cell (EC)-derived cytokine, has the strong ability to modulate signals delivered through innate immune receptors on dendritic cells (DCs), thus instructing the initiation of appropriate immune responses to T cells. In…
INTRODUCTION: Thymosin α 1 (Tα1) is a peptidic biological response modifier, which plays a significant role in activating and regulating various cells of the immune system. For the above-mentioned activities it is expected to exert a clinical benefit…
BACKGROUND AND AIMS: The immunomodulatory activity of thymosin α1 (Tα1) on innate immunity has been extensively described, but its mechanism of action is not completely understood. We explored the possibility that Tα1-stimulation could affect the for…
OBJECTIVES: The aim of this study was to characterize β and α thymosins and their proteoforms in various tissues and bodily fluids by mass spectrometry and to look at their association with a wide variety of pathologies. METHODS: A top-down proteomic…
OBJECTIVE: To analysis the effects of Talpha1 on the immune effector molecules in mouse immune system. METHODS: Sixty five BABL/c mice were divided into four groups: CsA group (n=20), Talpha1 group (n= 20), CsA+Talpha1 group (n=20) and control group…
Immune dysfunction is a major cause of mortality in septic patients. Current evidence indicates an important role for dendritic cells (DCs) in the pathophysiology of immune dysfunction, and these cells are potential targets of immunomodulation therap…
Anomalous diffusion is frequently described by scaled Brownian motion (SBM), a Gaussian process with a power-law time dependent diffusion coefficient. Its mean squared displacement is 〈x(2)(t)〉 ≃ 2K(t)t with K(t) ≃ t(α-1) for 0 < α < 2. SBM may provi…
Thymosin α1 (Tα1) is a naturally occurring thymic peptide used worldwide in clinical trials for the treatment of infectious diseases and cancer. The immunomodulatory activity of Tα1 on innate immunity effector cells has been extensively described, bu…
The phosphorescent efficiencies of the Ir(III) carbene complexes 1-3 with wide-range color tuning were focused on in this work. A DFT/TDDFT (density functional theory/time-dependent density functional theory) investigation on the geometries in the gr…
In the present study, the immunomodulatory and synergistic anti-tumor activity of thymosin α1-thymopentin fusion peptide (Tα1-TP5) was investigated in vivo. In addition, the potential receptor of Tα1-TP5 was investigated by surface plasmon resonance…
N(α)-terminal acetylation of peptides plays an important biological role but is rarely observed in prokaryotes. N(α)-terminal acetylated thymosin α1 (Tα1), a 28-amino-acid peptide, is an immune modifier that has been used in the clinic to treat hepat…
A serious limitation of numerous antitumor drugs is the incapacity to penetrate solid tumors. However, addition of an RGD fragment to peptide drugs might solve this problem. In this study, we explored whether the introduction of a permeability-enhanc…
There exists compelling experimental evidence in numerous systems for logarithmically slow time evolution, yet its full theoretical understanding remains elusive. We here introduce and study a generic transition process in complex systems, based on n…
BACKGROUND: Phyllanthus species for patients with chronic hepatitis B virus (HBV) infection have been assessed in clinical trials, but no consensus regarding their usefulness exists. When compared with placebo or no intervention, we were unable to id…
Thymosin alpha 1 (T α 1), which is composed of 28 amino acids, has been commercialized worldwide for its immune-modulatory and antitumor effects. T α 1 can stimulate T cell proliferation and differentiation from bone marrow stem cells, augment cell-m…
A recent randomized controlled clinical trial of the immunostimulatory agent thymosin alpha-1 was conducted and showed a trend toward improved survival in patients receiving the drug (P = 0.06). Although this was a relatively small study and the exac…
Thymosin alpha-1 (Tα1) has been used as an immune potentiator for treatment of immune deficiency diseases by injection administration. However, injection is inconvenient and may cause many side effects. In order to improve the administration convenie…
INTRODUCTION: Severe sepsis is associated with a high mortality rate despite implementation of guideline recommendations. Adjunctive treatment may be efficient and require further investigation. In light of the crucial role of immunologic derangement…
