Example sentences for: infectivity
How can you use “infectivity” in a sentence? Here are some example sentences to help you improve your vocabulary:
Data presented here show that CAP remains bound to HIV-1 after removal of unreacted compound, impairing virus infectivity due to blockade of binding sites for cellular coreceptors CXCR4 and CCR5.
Virus infectivity can be enhanced by treatment of cells with MAPK stimulators, such as serum and phorbol myristate acetate, as well as by coexpression of constitutively activated Ras, Raf, or MEK in the absence of extracellular stimulation [ 61 ] . Also, following infection, efficient disengagement of the reverse transcription complex from the cell membrane and subsequent nuclear translocation, requires phosphorylation of the reverse transcription complex components by ERK/MAPK; demonstrating a critical regulation of an early step in HIV-1 infection by the host cell MAPK signal transduction pathway [ 62 ] . Therefore, Tat down-regulation of the MAPK pathway in latent cells implies that much of the host signal transductions connected to activation are down-regulated, and at the same time, these cells may be refractory to subsequent infection by other viruses.
Author 3 SJ developed monoclonal antibody NC-1 and was involved in studies on the gp41 six helix bundles and on synergism between CAP and sCD4 for inhibition of HIV-1 infectivity.
Such activity was reported for dextran sulfate after 2 h incubation with HIV-1 [ 2 ] but results of other studies indicated that dextran sulfate failed to neutralize virus infectivity [ 4 10 ] . Inactivation of HIV-1 by carrageenan was reported in a review article [ 18 ] . BufferGel is virucidal against HIV-1 by providing a buffered low pH environment (pH 3.9 [ 25 ] ), but virus inactivation might be incomplete and possibly compromised by minor pH increases due to the presence of seminal fluid [ 40 ] . To be effective in preventing infection by direct virus inactivation, anti-HIV-1 microbicides must be virucidal against both X4 and R5 viruses, utilizing CXCR4 and CCR5 as coreceptors [ 39 41 ] , respectively, R5 HIV-1 being most frequently sexually transmitted.
The percentage of residual infectivity after CAP treatment was calculated from calibration curves relating absorbance (corresponding to formazan for HIV-1 IIIB and p24 antigen for HIV-1 BaL, respectively) to virus dilutions of untreated viruses.
