The peripheral immune system can promote either immunity or tolerance when presented with new antigens. Current knowledge withholds that populations of suppressor or regulatory T cells (T(reg) cells) constitute a pivotal mechanism of immunological to…
Thymosin alpha-1 (Talpha1) is a molecule retaining pleiotropic effects toward several pathological conditions, especially acting as a modulator of immune response and inflammation. However, molecular mechanisms underlying the peculiar, wide-range act…
Thymosin alpha 1, originally isolated as the compound responsible for reconstitution of immune function in thymectomized animal models, has enjoyed a wide-ranging clinical development program over the past decades, extending across multiple companies…
The hepatitis C virus (HCV) is a global public health problem, with chronic infection leading to development of cirrhosis, end-stage liver disease and hepatocellular carcinoma (HCC). Treatment of HCV is suboptimal with overall response rates of sligh…
Thymalfasin exhibited an immunomodulatory and a direct antiviral mechanism of action. The low rate of sustained response of chronic hepatitis with current therapies, underscores the need for new therapeutic options. It has been suggested that thymalf…
The current standard therapy for the treatment of chronic hepatitis C virus (HCV) is the combination of peginterferon and ribavirin, although many patients fail to clear the virus and their retreatment options are still unsatisfactory. Thymosin alpha…
We designed a phase I/II clinical study to determine safety and efficacy of thymosin alpha1 (Talpha1) administration in recipients of one HLA haplotype (haploidentical) stem cell transplants for hematologic malignancies. Talpha1 administration did no…
Thymosin alpha1 (Talpha1) is a 28 amino acid biologically active protein with pleiotropic immune enhancing activity. IRX-2 is a primary cell-derived biologic containing multiple cytokines that enhance dendritic cell maturation, promote T-cell growth…
DATA SOURCES: The Cochrane Oral Health Group's Trials Register, Cochrane CENTRAL, Medline and Embase were consulted, along with the websites www.clinicaltrials.gov and www.controlled-trials.com and reference lists of identified articles. There were n…
The purpose of this study was to develop poly(lactide-co-glycolide) (PLGA) based in situ forming implants (ISFI) for controlled release of thymosin alpha 1 (Talpha1). The ISFI was prepared by dissolving PLGA in N-methyl-2-pyrrolidone (NMP) or mixture…
Thymosin alpha 1 (Tα1), a 28-amino acid peptide, was first described and characterized from calf thymuses in 1977. This peptide can enhance T-cell, dendritic cell (DC) and antibody responses, modulate cytokines and chemokines production and block ste…

We study mixing of isothermal fluids by controlling the global hydrodynamic entropy <s> . In particular, based on the statistical coupling between the evolution of <s> and the global viscous dissipation <ϵ> , we analyze stirring protocols such that <…
The Fifth Annual Immunotherapeutics and Vaccine Summit (ImVacS), held in Boston, included topics covering new developments in the field of adjuvants and delivery systems for vaccines. This conference report highlights selected presentations on improv…
The purpose of this study was to explore the regulatory effect of thymosin α1 (Tα1) on expression of TOLL-like receptor 9 (TLR9)/indoleamine2, 3-dioxygenase (ido) mRNA in bone marrow mesenchymal stem cells (MSC) from children with aplastic anemia (AA…
Thymosin-α(1) (TA(1)) has been shown to be effective treatment for chronic hepatitis B virus (HBV) infection. This study investigated the immune response after TA(1) monotherapy in 25 HBV e antigen (HBeAg)-positive patients randomized to receive eith…
Hypothalamic GHRH controls the release of GH from the pituitary gland and also acts as a growth factor in a variety of cancers. The mitogenetic activity of GHRH is exerted through the binding to the pituitary type receptor (pGHRH-R) and its splice va…
We investigated the effect of a GHRH antagonist, MIA-602on the metastatic cascade in vitro of three human cancers, DBTRG-05 glioblastoma, MDA-MB-468 estrogen-independent breast, and ES-2 clear cell ovarian cancer. GHRH receptors and their main splice…
The effects of new growth hormone-releasing hormone (GHRH) antagonists JMR-132 and MIA-602 and their mechanism of action were investigated on 2 human glioblastoma cell lines, DBTRG-05 and U-87MG, in vitro and in vivo. GHRH receptors and their main sp…
