چکیده

objective: in recent decades, β-glucans have been used as important complementary and alternative medicines for numerous immunocompromised individuals and those with end stage of cancer terminal. the most active form of β-glucans is β(1,3)d-glucan and its  most common source is cell wall of candida albicans. recently it has been introduced as a nano particle design to be used as a carrier for drug delivery. the current study researches a rapid method for the extraction of β(1,3)d-glucans. methods: the present study was conducted attarbiatmodaresmedicaluniversity in 2012. candida solubilized β-glucans were obtained by oxidation of the cell wall with sodium hypochlorite and sodium hydroxide. the particle part could be solubilized by treatment with dimethylsulfoxide (dmso) and zymolyase digestion to extract β(1,3)d-glucan. the soluble fractions were lyophilized. we performed the callose test to verify the presence of β(1,3)d-glucans. solubilized fractions were dissolved in d2o and 1h-nmr spectra were measured. results: the soluble β(1,3)d-glucan fraction which was derived from 1 g of dried candida albicans germ tube weighed 190 mg. β(1,3)d-glucan was verified by the callose test and 1h-nmr test compared with curdlan (standard). 1h-nmr spectra verified the existence of β(1,3)d-glucan in the final product. conclusion: in the present study, extraction of β(1,3)d-glucan by oxidation of the cell wall using sodium hypochlorite yielded more pure β(1,3)d-glucans in comparison with other extraction methods. thus it might represent a rapid method of extraction.

The Effects of Candida Albicans Cell Wall Protein Fraction on Dendritic Cell Maturation

Back ground: Candida albicans is a member of the normal human microflora. C. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in C. albicans interaction with the host immune system. Major components of C. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...

Comparison of cell wall proteins in putative Candida albicans & Candida dubliniensis by using modified staining method & SDSPAGE

 Background: Candida species are among the most common causes of opportunistic fungal diseases. Among Candida species, Candida albicans is responsible for most infections. Having many strains, C. albicans is very polymorph. C. dubliniensis is very similar to albicans species both morphologically and physiologically. For an infection to occur, cell wall proteins play an important role as they en...

-Glucan of Candida albicans cell wall causes the subversion of human monocyte differentiation into dendritic cells

The functional consequences of treating human monocytes with purified and chemically characterized Candida albicans -glucan—a major microbial pathogen associated molecular pattern—on their differentiation into dendritic cells (DC) were investigated. We show here that -glucan-treated monocytes differentiated into mature DC (Glu-MoDC) with altered phenotype and functional behavior, similarly to D...

Candida albicans cell wall proteins.

The Candida albicans cell wall maintains the structural integrity of the organism in addition to providing a physical contact interface with the environment. The major components of the cell wall are fibrillar polysaccharides and proteins. The proteins of the cell wall are the focus of this review. Three classes of proteins are present in the candidal cell wall. One group of proteins attach to ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

New mechanical disruption method for extraction of whole cell protein from Candida albicans.

Cell disruption or lysis is a crucial step to obtain cellular components for various biological studies. We subjected different concentrations of Candida albicans to 5, 10, 15 and 20 cycles of disruption. The degree of cell lysis was observed using light microscopy and the yields obtained were measured and analysed. The optimum extraction with 1 x 10(10) yeast cells/ml was achieved after 5 cycl...
