Introduction Chronic Musculoskeletal Pain (MSP) in children can be due to various non-inflammatory conditions, such as the benign joint hypermobility syndrome (BJHS) or idiopathic MSP (IMSP). MSP heavily influences patient’s quality of life and is often misdiagnosed or included in the vast category of unspecific MSP. A careful differential diagnosis and knowledge of possible risk factors are ne...

A full-length cDNA clone of a previously unidentified serine protease, myelencephalon-specific protease (MSP), has been isolated by using a PCR cloning strategy and has been shown to be expressed in a nervous system and spinal cord-specific pattern. Sequence analysis demonstrated that MSP is most similar in sequence to neuropsin, trypsin, and tissue kallikrein and is predicted to have trypsin-l...

Cerebral malaria (CM) and severe malarial anemia (SMA) are 2 major causes of death in African children infected with Plasmodium falciparum. We investigated levels of naturally acquired antibody to conserved and variable regions of merozoite surface protein (MSP)-1 and MSP-2, apical membrane antigen (AMA)-1, and rhoptry-associated protein 1 in plasma samples from 126 children admitted to the hos...

The 42-kDa carboxyl-terminal processing fragment of Plasmodium falciparum merozoite surface protein 1 (MSP-1(42)) is an anti-erythrocytic stage malaria vaccine candidate. In this study, MSP-1(42) was expressed by using the Bombyx mori nuclear polyhedrosis virus-silkworm expression system, and the antigenicity and immmunogenicity of the recombinant protein, Bmp42, were evaluated. The average yie...

Genetic characteristics of Plasmodium falciparum may play a role in the treatment outcome of malaria infection. We have studied the association between diversity at the merozoite surface protein-1 (msp-1), msp-2, and glutamate-rich protein (glurp) loci and the treatment outcome of uncomplicated falciparum malaria patients along the Thai-Myanmar border who were treated with artemisinin derivativ...

The major outer sheath protein (Msp) of Treponema denticola inhibits neutrophil polarization and directed chemotaxis together with actin dynamics in vitro in response to the chemoattractant N-formyl-methionine-leucine-phenylanine (fMLP). Msp disorients chemotaxis through inhibition of a Rac1-dependent signaling pathway, but the upstream mechanisms are unknown. We challenged murine bone marrow n...

Macrophage stimulating protein (MSP) is a pleiotropic growth factor that signals via the Ron receptor tyrosine kinase. We report that Ron mRNA is expressed by NGF-dependent sensory and sympathetic neurons and that these neurons survive and grow with MSP at different stages of development. Whereas NGF-dependent sensory neurons become increasingly responsive to MSP with age, sympathetic neurons e...

b ackground: the main goal of present study was to detect polymorphism in msp-1 gene which is a major blood stage candidate for vaccine in plasmodium vivax by single strand conformational poly- morphism-polymerase chain reaction (sscp-pcr). m ethods: during 2008 to 2010 fifty samples were collected from iranian patients with p. vivax in hormozgan province, southern iran. all of the samples were...

The major outer sheath protein (Msp) of Treponema denticola perturbs actin dynamics in fibroblasts by inducing actin reorganization, including subcortical actin filament assembly, leading to defective calcium flux, diminished integrin engagement of collagen, and retarded cell migration. Yet, its mechanisms of action are unknown. We challenged Rat-2 fibroblasts with enriched native Msp. Msp acti...
