Stepwise Enzymatic-Dependent Mechanism of Ebola Virus Binding to Cell Surface Receptors Monitored by AFM.

Ebola virus (EBOV) is responsible for several outbreaks of hemorrhagic fever with high mortality, raising great public concern. Several cell surface receptors have been identified to mediate EBOV binding and internalization, including phosphatidylserine (PS) receptors (TIM-1) and C-type lectin receptors (DC-SIGNR). However, the role of TIM-1 during early cell surface binding remains elusive and in particular whether TIM-1 acts as a specific receptor for EBOV.

Comparative analysis of the complete nucleotide sequences of measles, mumps, and rubella strain genomes contained in Priorix-Tetra and ProQuad live attenuated combined vaccines.

Measles, mumps, and rubella are three common viral childhood diseases that can have serious complications. Active immunization against these diseases became possible with the development of live attenuated virus vaccines in the late 1960s. Vaccines against these three diseases were combined into trivalent (Priorix, GlaxoSmithKline Biologicals and M-M-R(II), Merck & Co.

Complete DNA sequences of two oka strain varicella-zoster virus genomes.

Varicella-zoster virus (VZV) is a herpesvirus and is the causative agent of chicken pox (varicella) and shingles (herpes zoster). Active immunization against varicella became possible with the development of live attenuated varicella vaccine. The Oka vaccine strain was isolated in Japan from a child who had typical varicella, and it was then attenuated by serial passages in cell culture.
