Studies

In recent years many studies have stressed the importance of using biological response modifiers (BRMs) in the treatment of different conditions of immune-impairment correlated with ageing, cancer and infectious diseases. In particular, the use of di…

Axonal regrowth after injury is accompanied by changes in the expression of tubulin, but the contributions of substrate molecules and neurotrophic factors in regulating these changes in vivo are not known. Adult rat retinal ganglion cells (RGCs) were…

The gene encoding the bovine guanylate cyclase isoform E (GC-E) was isolated as a single 18 kb genomic clone and shown to have 20 exons and 19 introns. Comparison of the structure of the GC-E gene with structures of other membrane guanylate cyclase g…

Because current standard therapy of chronic hepatitis C with alpha interferon is less than ideal, numerous other approaches have been studied. Iron in the liver, particularly that found in vascular endothelial cells of portal tracts, has been associa…

This study investigated changes in gene expression in lumbar dorsal root ganglia (DRG), contralateral and ipsilateral to a sciatic nerve crush in control and streptozotocin (STZ)-induced diabetic rats. After 10 weeks of diabetes, the left sciatic ner…

Hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis delta virus (HDV) are associated with clinically significant chronic infection that may lead to the development of cirrhosis or even hepatocellular carcinoma (HCC). Intervention at the ea…

Rubrospinal neurons (RSNs) undergo a marked atrophy in the second week after cervical axotomy. This delayed atrophy is accompanied by a decline in the expression of regeneration-associated genes such as GAP-43 and Talpha1-tubulin, which are initially…

During the past century of research on the thymus, the fact that every mammalian thymus undergoes marked morphological changes during the complex process of aging has been defined as a basic histogenetical rule. In characterizing the physiological (i…

A set of CTL-lines in the system differing in the whole H-2 complex, as well as in distinct subregions of H-2, was established. These lines were routinely tested in Cr51-release assay to insure that they retained lytic activity and antigen-specificit…

OBJECTIVE: Prothymosin-alpha, the precursor of thymosin-alpha1, may play a role in cell proliferation, and the plasma level of thymosin-alpha1 may reflect the degree of proliferation of the tumor cells. METHODS: Recently, a new sandwich immunoradiome…

Antimicrobial peptides of several structural classes have been found in phagocytes and epithelial cells of many animals. The broadly microbicidal protegrins (PG1, -2, and -3) were originally isolated as 16 to 18-amino-acid peptides from pig neutrophi…

The epithelia constitute a major barrier to the environment and provide the first line of defense against invading microbes. Antimicrobial peptides are emerging as participants in the defense system of epithelial barriers in general. Originally we is…

hCAP-18 is a newly described protein of human neutrophilic granulocytes which belongs to the cathelicidin family of antimicrobial proteins. Members of this protein family share a common N-terminal sequence followed by a highly diverse antimicrobial,…

Neutrophils contain various antibacterial polypeptides and proteins in the granules that contribute to the killing of microorganisms. Recently, we have purified a cationic antibacterial polypeptide of 11 kDa (CAP11) from guinea pig neutrophil granule…

hCAP-18 is the only human member of the antibacterial and endotoxin-binding family of proteins known as cathelicidins. The antibacterial and endotoxin binding domains reside in the C-terminal 37 amino acids of the protein (LL-37) and this is believed…

Cathelicidins are a group of myeloid antimicrobial peptide precursors found in a variety of mammalian species. Transcripts of this family show a highly conserved 5' region corresponding to the 5' untranslated region, signal peptide and propiece, and…
