Human peripheral blood mononuclear cells (PBMC) can be infected in vitro with sera of hepatitis C virus (HCV)-infected patients. We have treated pools of PBMC with dextran sulfate MW 8,000, before infection with various HCV(+) sera. When the cells were treated with dextran sulfate 10-3 M, HCV RNA was no longer detectable after infection with all HCV genotypes tested. When the cells incubated with dextran sulfate 10-3 M and 10-4 M were maintained in culture for 4 weeks, no significant HCV replication could be observed. Our data suggest that dextran sulfate inhibits the attachment of HCV to the cell surface, since the HCV RNA detection was similar to control cells when dextran sulfate was added after infection.

UI	MeSH Term	Description	Entries
D007963	Leukocytes, Mononuclear	Mature LYMPHOCYTES and MONOCYTES transported by the blood to the body's extravascular space. They are morphologically distinguishable from mature granulocytic leukocytes by their large, non-lobed nuclei and lack of coarse, heavily stained cytoplasmic granules.

D000327	Adsorption	The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily.	Adsorptions
D012367	RNA, Viral	Ribonucleic acid that makes up the genetic material of viruses.	Viral RNA
D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D016264	Dextran Sulfate	Long-chain polymer of glucose containing 17-20% sulfur. It has been used as an anticoagulant and also has been shown to inhibit the binding of HIV-1 to CD4-POSITIVE T-LYMPHOCYTES. It is commonly used as both an experimental and clinical laboratory reagent and has been investigated for use as an antiviral agent, in the treatment of hypolipidemia, and for the prevention of free radical damage, among other applications.
