Voltage-gated K+ channels contain six membrane spanning segments and a pore-forming domain. We used site-directed mutation to examine the role of specific amino acids in the extracellular region of the pore in Kv1.2. When expressed in CHO cells, a K+ current was not observed for mutants S356A, S360A, T383A and T384A. However, coexpression of the Kvβ2(More)
Human parvovirus B19 is a clinically important pathogen in both children and adults. In adults, it frequently causes acute and chronic arthritis, which may be related to persistent infection. The effect of the capsid of human parvovirus B19 on monocytes, which are thought to be responsible for the first line of defense against parvoviral infection, is not(More)
An infecting strain VLA2/18 of Campylobacter jejuni was obtained from an individual with campylobacteriosis and used to prepare chicken sera by experimental infection to investigate the role of serum anti-ganglioside antibodies in Guillain-Barré syndrome. Both sera of the patient and chicken contained anti-ganglioside antibodies and anti-Lipid A(More)
