Schistosomiasis is an endemic disease in Egypt caused by the trematode Schistosoma which has different species. c the best known form of chronic disease with a wide range of clinical manifestations. The pathogenesis of schistosomiasis is related to the host cellular immune response. This leads to granuloma formation and neo angiogenesis with subsequent periportal fibrosis manifested as portal hypertension, splenomegaly and esophageal varices. Intestinal schistosomiasis is another well identified form of chronic schistosomal affection.

The C-terminus of thea-chain of tubulin is subject to reversible incorporationof tyrosineby tubulin tyrosine ligase and removal by tubulin carboxypeptidase. Thus, microtu-bules rich in either tyrosinated or detyrosinated tubulin can coexist in the cell. Substitution of the terminal tyrosine by 3-nitrotyrosine has been claimed to cause microtubule dys-function and consequent injury of epithelial lung carcinoma A549 cells. Nitrotyrosine is formed in cells by nitration of tyrosine by nitric oxide-derived species....

The heat-stable enterotoxin peptides (ST) produced by enterotoxigenicEscherichia coliare one of the major causes of transitory diarrhea in the developing world. Toxin bind-ing to its receptor, guanylyl cyclase C (GC-C), results in receptor activation and the production of high intracellular levels of cGMP. GC-C is expressed in two differentially glycosylated forms in intestinal epithelial cells. Prolonged exposure of human colonic cell lines to ST peptides induces cellular refractoriness to the ST peptide, in terms of intra-cellular cGMP accumulation....

Halobacterium salinarumdisplays four distinct kinetic forms of M-intermediate in its bacteriorhodopsin photocycle. In wild-type, there are mainly two species with time constants near 2 and 5 ms. Under various kinds of stress, two other species arise with time constants near 10 and 70 ms. We show that these four species are interconvertible. Increases in membrane hydrophobicity convert the slower to faster forms. Perturbations caused by Triton X-100 or mutations convert faster to slower forms.

Senile plaques, the invariable hallmark and likely proximal cause of Alzheimer’s disease (AD), are structured deposi-tions of the 40- and 42-residue forms of the Abpeptide. Conversely, diffuse plaques, which are not associated with neurodegeneration, consist mainly of unstructured Ab42. We have investigated the interaction between Ab40 and Ab42 through an assay, which involves labeling both vari-ants with an environment-sensitive fluorophore.

Metachromatic leukodystrophy is a lysosomal storage disorder caused by a deficiency of arylsulfatase A (ASA). Biosynthesis studies of ASA with vari-ous structure-sensitive monoclonal antibodies reveal that some epitopes of the enzyme form within the first minutes of biosynthesis whereas other epi-topes form later, between 10 and 25 min. When we investigated 12 various ASAs, with amino acid substitutions according to the missense mutations found in metachromatic leukodystrophy patients, immunoprecipitation with monoclonal antibodies revealed folding deficits in all 12 mutant ASA enzymes....

The dementia familial encephalopathy with neuroserpin inclusion bodies (FENIB) is caused by point mutations in the neuroserpin gene.We have shown a correlation between the predicted effect of the mutation and the number of intracerebral inclusions, and an inverse relationshipwith the age of onset of disease. Our previous work has shown that the intraneuronal inclusions in FENIB result from the sequential interactionbetween the reactive centre loopofone neuroserpin molecule withb-sheet A of the next. ...

Homocysteine (Hcy) is anonprotein-forming sulphur amino acid that plays an important role in remethylation and trans-sulphuration processes. In recent years, it has been suggested that increased levels of plasma Hcy may play a role in the pathogenesis of various diseases, particularly at the cardiovascular level. The pathogenic mechanism of hyperhomocysteinemia, however, has not been clarified.

The spontaneous acquisition of resistance to a variety of unrelated cytotoxic compounds has important implications in medical treatment of infectious diseases and anticancer therapy. In the yeast Saccharomyces cerevisiaethis pheno-menon is caused by overexpression of membrane efflux pumps and is called pleiotropic drug resistance. We have found that allelic forms of the genes for the transcription activators Pdr1p and Pdr3p, designated PDR1-12and PDR3-33,respectively, mediate resistance to diazaborine....

Two mutants ofChlamydomonas reinhardtii, mf1andmf2, characterized by a marked reduction in their phosphatidyl-glycerol content together with a complete loss in itsD 3 -trans hexadecenoic acid-containing form, also lost photosystemII (PSII) activity. Genetic analysis of crosses betweenmf2and wild-type strains shows a strict cosegregationof thePSII and lipid deficiencies, while phenotypic analysis of phototrophic revertant strains suggests that one single nuclear mutation is responsible for the pleiotropic phenotype of the mutants....

UDP-galactose 4-epimerase (GALE, EC 5.1.3.2) catalyses the interconver-sion of UDP-glucose and UDP-galactose. Point mutations in this enzyme are associated with the genetic disease, type III galactosemia, which exists in two forms – a milder, or peripheral, form and a more severe, or general-ized, form.

Mutations in neuroserpin anda1-antitrypsin cause these proteins to form ordered polymers that are retained within the endoplasmic reticulum of neurones and hepatocytes, respectively. The resulting inclusions underlie the dementia familial encephalopathy with neuroserpin inclusion bodies (FENIB) and Z a1-antitrypsin-associated cirrhosis.

Mutations in the human Crumbs homologue 1 (CRB1) gene are a frequent cause of various forms of retinitis pigmentosa. The CRB1–membrane-asso-ciated palmitoylated protein (MPP)5 protein complex is thought to organ-ize an intracellular protein scaffold in the retina that is involved in maintenance of photoreceptor–Mu¨ller glia cell adhesion.

Prion diseases are neurodegenerative disorders which cause Creutzfeldt– Jakob disease in humans, scrapie in sheep and bovine spongiform encephalopathy in cattle. The infectious agent is a protease resistant iso-form (PrP Sc ) of a host encoded prion protein (PrP C ). PrP Sc proteins are characterized according to size and glycoform pattern.

Transmissible spongiform encephalopathies are fatal neurodegenerative dis-eases that are caused by unconventional pathogens and affect the central nervous system of animals and humans. Several different forms of these dis-eases result from natural infection (i.e. exposure to transmissible spongiform encephalopathy agents or prions, present in the natural environment of the respective host).

Rare, inherited mutations causing familial forms of Parkinson’s disease have provided insight into the molecular mechanisms that underlie the genetic and sporadic forms of this disease. Loss of protein function result-ing from autosomal-recessive mutations in PTEN-induced putative kinase 1 (PINK1), Parkin and DJ-1 has been linked to mitochondrial dysfunction, accumulation of abnormal and misfolded proteins, impaired protein clear-ance and oxidative stress.
