The treatment of 17 patients having chronic obstructive bronchitis with a combined vaccine resulted in a rise in the number of T lymphocytes and T suppressors, as well as a simultaneous increase in their functional activity, in these patients. Moreover, an increase in the ingestive activity of neutrophils and in the concentration of immune complexes was registered. Treatment with the vaccine containing Staphylococcus aureus, Klebsiella pneumoniae, Proteus and Escherichia coli antigens facilitated an increase in the titers of antibodies to most antigens contained in the vaccine and in the resistance of the body to infection. Vaccinal therapy made it possible to achieve a significant prolongation of the period of remission.

Background: Dysregulated GABA/somatostatin (SST) signaling has been implicated in psychiatric and neurodegenerative disorders. The inhibition of excitatory neurons by SST+ interneurons, particularly through α5-containing GABAA receptors (α5-GABAAR), plays a crucial role in mitigating cognitive functions. Previous research demonstrated that an α5-positive allosteric modulator (α5-PAM) mitigates working memory deficits and reverses neuronal atrophy in aged mice.

Background: Astrocytes, a major glial cell in the central nervous system (CNS), can become reactive in response to inflammation or injury, and release toxic factors that kill specific subtypes of neurons. Over the past several decades, many groups report that reactive astrocytes are present in the brains of patients with Alzheimer's disease, as well as several other neurodegenerative diseases. In addition, reactive astrocyte sub-types most associated with these diseases are now reported to be present during CNS cancers of several types.

Administration of antiseizure medicines (ASMs) to AD patients with epileptiform activity may improve cognition (Vossel et al.
View Article and Find Full Text PDFBackground: Early-onset Alzheimer's disease (EOAD) associated with amyloid precursor protein (APP) duplications or presenilin (PSEN) variants increases risk of seizures. Targeting epileptiform activity with antiseizure medicine (ASM) administration to AD patients may beneficially attenuate cognitive decline (Vossel et al, JAMA Neurology 2021). However, whether mechanistically distinct ASMs differentially suppress seizures in discrete EOAD models is understudied (Lehmann et al, Neurochem Res 2021).
View Article and Find Full Text PDFBackground: There are no cures for Alzheimer's disease (AD), a progressive neurodegenerative disorder characterized by elevation of beta-amyloid and tau proteins besides neuronal death and causing cognitive impairment. Phosphodiesterase 5 (PDE5) is a cyclic guanosine monophosphate-degrading enzyme involved in numerous biological pathways including those relevant to memory formation. PDE5 inhibition offers the potential to attenuate AD progression by acting at the downstream level of beta-amyloid and tau elevation.
