Merozoites of the malaria parasite Plasmodium falciparum expose at their surface a large multiprotein complex, composed of proteolytically processed, noncovalently associated products of at least three genes, msp-1, msp-6, and msp-7. During invasion of erythrocytes, this complex is shed from the surface except for a small glycosylphosphatidylinositol-anchored portion originating from MSP-1. The...
Macrophage stimulating protein (MSP), which is secreted as biologically inactive pro-MSP, is activated to MSP by cleavage at a single peptide bond. Our objectives were to determine the form of MSP in circulating blood and to study proteolytic activation of pro-MSP by its target cell. Western blot of immunoaffinity-purified serum MSP showed that all the protein was pro-MSP, without detectable MS...
background genetic diversity has provided plasmodium falciparum with the potential capacity of avoiding the immune response, and possibly supported the natural selection of drug or vaccine-resistant parasites. merozoite surface protein-3 (msp-3) has been used to develop vaccines and investigate the genetic diversity regarding p. falciparum malaria in iran. objectives the main goal of this study...
Beta-microseminoprotein (MSP) is one of the most abundant proteins secreted by the prostate gland. Because MSP is also synthesized in nonreproductive organs, the establishment of a solid relationship between the levels of MSP in serum and semen is crucial for future studies connecting MSP with aging or diseases of the prostate gland. We developed a specific, competitive, europium-based immunoas...
Background: Plasmodiom falciparum MSP-2 is taken into accout as one of the candidates of vaccine agaist malaria and various studies indicated immunizing effect of different domains of the molecule. Monoclonal antibody against MSP-2 is a confident and definite method to confirm this Immunization. Materials and Methods: P. falciparum Parasite was Prepared in a Culture in CludingRPMI1640 and Schi...
The major sperm protein (MSP) is the central cytoskeletal element required for actin-independent motility of nematode spermatozoa. MSP has a dual role in Caenorhabditis elegans reproduction, functioning as a hormone for both oocyte meiotic maturation and ovarian muscle contraction. The identification of the signaling function of MSP raised the question, how do spermatozoa, which are devoid of r...
OBJECTIVE Despite well-known adverse health effects of maternal smoking during pregnancy (MSP), it is still unclear if MSP varies geographically and if neighborhood socioeconomic deprivation (SED) plays an important role in MSP. This study aims to investigate small-area geographic variation in MSP and examine the association of SED with MSP. METHODS The Missouri Adolescent Female Twin Study (...
BACKGROUND Promoter hypermethylation has emerged as a promising cancer biomarker. Currently, a large variety of quantitative and non-quantitative techniques is used to measure methylation in clinical specimens. Here we directly compared three commonly used methylation assays and assessed the influence of tissue fixation, target sequence location and the amount of DNA on their performance. MET...
We have examined the capacity of the major secretory protein (MSP) of Legionella pneumophila to induce humoral, cell-mediated, and protective immunity in a guinea pig model of Legionnaires' disease. MSP was purified to homogeneity by ammonium sulfate precipitation, molecular sieve chromatography, and ion-exchange chromatography. The purified MSP was nonlethal and nontoxic to guinea pigs upon su...
Major surface protease (MSP), also called GP63, is a virulence factor of Leishmania spp. protozoa. There are three pools of MSP, located either internally within the parasite, anchored to the surface membrane, or released into the extracellular environment. The regulation and biological functions of these MSP pools are unknown. We investigated here the trafficking and extrusion of surface versu...
