Alzheimer's disease (AD) is characterized by progressive neurodegeneration and is the most common cause of dementia. Immunotherapy has recently been regarded as a potential treatment for AD. This stems from the fact that the clinical and pathological findings from the active AD vaccine trial suggests that such vaccine therapy may be effective for AD. However, this trial was halted because of th...

The survival of 7 of 8 patients with Ebola virus (EBOV) infection after transfusions of convalescent-phase blood during a 1995 outbreak of EBOV infection is frequently cited as evidence that passive immunotherapy is a viable treatment option. To test whether whole-blood transfusions were more efficacious than passively administered immunoglobulins or monoclonal antibodies, we transfused convale...

Experimental pneumococcal pneumonia in leukopenic BALB/c mice enabled evaluation of passive immunotherapy with human polyvalent intravenous immune globulin (IVIG) given intravenously or intranasally and with F(ab')2 fragments administered intranasally. For intravenous and intranasal IVIG, the respective effective doses were < 5 but > 0.5 mg/kg and < 250 but > 2.5 micrograms/kg. For F(ab')2 frag...

Alzheimer's disease (AD) is a neurodegenerative disorder that impairs memory and cognition. One of the major neuropathological hallmarks is the accumulation of the extracellular senile plaques that are mainly composed of amyloid beta (Abeta) protein. Plaques are associated with synapse loss, dystrophic neurites and altered neurite trajectories. A reversal of such morphological changes has been ...

Objective(s): Pseudomonas aeruginosa infections such as keratitis are considered among the major health problems worldwide due to the complexity of pathogenesis and antibiotic resistance crisis, thus, finding new effective approaches for prevention and treatment of the infections seem to be still vital. In this report, we aimed to investigate the therapeutic effects of topical administration of...

The harmful COVID-19 pandemic caused by the SARS-CoV-2 coronavirus imposes scientific community to develop or find conventional curative drugs, protective vaccines, passive immune strategies rapidly and efficiently. Passive immunity is based on recovering hyper-immune plasma from convalescent patients, monoclonal antibodies with elevated titer of neutralizing high antiviral activity, that have ...

Vaccination against nicotine reduces the behavioral effects of nicotine in rats, and it is under clinical evaluation as a treatment for tobacco addiction. Efficacy is limited by the need for high serum nicotine-specific antibody (NicAb) levels, and currently available nicotine vaccines do not uniformly generate the required NicAb levels. Passive immunization with a nicotine-specific monoclonal ...

Alzheimer disease (AD) is the most prevalent form of dementia of adult-onset, characterized by progressive impairment in cognition and memory. There is no cure for the disease and the current treatments are only symptomatic. Drug discovery is an expensive and time-consuming process; in the last decade no new drugs have been found for AD despite the efforts of the scientific community and pharma...
