Virus-specific neutralization by a soluble non-immunoglobulin factor found naturally in normal mouse sera.

Binding and degradation of soluble immunoglobulin aggregates by mouse mononuclear phagocytes--stimulation by colony-stimulating factor.

Virus Neutralization Experiments with Rosenow's and Pettit's Antipoliomyelitic Sera

1. The Rosenow antistreptococcic poliomyelitis serum concentrated or unconcentrated does not neutralize the virus of poliomyelitis as tested in monkeys. 2. The Pettit antipoliomyelitis horse serum neutralizes the virus only occasionally. 3. "Immune" sheep sera prepared according to the method of Pettit have not neutralized virus even when the normal sera of the same animal have given neutraliza...

Human papilloma virus infection in non-cancerous versus normal esophageal tissue samples by endoscopy

Abstract Background: Cancers are the second most common cause of non-accidental deaths in Iran, after cardiovascular mortality. Although most cases of esophageal squamous cell carcinoma (ESCC) in the USA and western populations have been attributed to high levels of exposure to tobacco and alcohol, but in Iranian populations the other risk factors especially infectious agents have been postula...

Intracellular neutralization of influenza virus by immunoglobulin A anti-hemagglutinin monoclonal antibodies.

Traditionally, immunoglobulin A (IgA) was thought to neutralize virus by forming complexes with viral attachment proteins, blocking attachment of virions to host epithelial cells. Recently we have proposed an intracellular action for dimeric IgA, which is actively transported through epithelial cells by the polymeric immunoglobulin receptor (pIgR), in that it may be able to bind to newly synthe...

Pseudotypes of human T-cell leukemia virus types 1 and 2: neutralization by patients' sera.

Pseudotypes of vesicular stomatitis virus (VSV) bearing envelope antigens of human T-cell leukemia virus (HTLV) types 1 and 2 were prepared by propagating VSV in cells lines productively infected with HTLV. Plaque assays of VSV (HTLV) pseudotypes were employed to determine the presence of (i) HTLV receptors on cells and (ii) neutralizing antibodies in the serum of patients with adult T-cell leu...
