Preliminary Evidence for the Role of Fungi, Specifically Chaetomium, in Gulf War Illness.

Introduction: For veterans of the Persian Gulf War (1990-1991), dozens of possible causes for their illness have been proposed. We hypothesize that all may be correct. These may have weakened the immunity of the military personnel to fungal pathogens in the soil.

Active immunity induced by passive IgG post-exposure protection against ricin.

Therapeutic antibodies can confer an instant protection against biothreat agents when administered. In this study, intact IgG and F(ab')2 from goat anti-ricin hyperimmune sera were compared for the protection against lethal ricin mediated intoxication. Similar ricin-binding affinities and neutralizing activities in vitro were observed between IgG and F(ab')2 when compared at the same molar concentration.

Conformation-dependent high-affinity potent ricin-neutralizing monoclonal antibodies.

Ricin is a potential biothreat agent with no approved antidote available for ricin poisoning. The aim of this study was to develop potent antibody-based antiricin antidotes. Four strong ricin resistant hybridoma clones secreting antiricin monoclonal antibodies (mAbs) were developed.

Humanization and characterization of an anti-ricin neutralization monoclonal antibody.

Ricin is regarded as a high terrorist risk for the public due to its high toxicity and ease of production. Currently, there is no therapeutic or vaccine available against ricin. D9, a murine monoclonal antibody developed previously in our laboratory, can strongly neutralize ricin and is therefore a good candidate for humanization.
