Proline-rich polypeptide complex (PRP) and its constituent nonapeptide (NP) possess immunoregulatory and procognitive properties. PRP in the form of sublingually administered tablets called Colostrinin™ improves the outcome of patients with Alzheimer’s disease (AD). Free radical-induced oxidative stress has been implicated in the pathogenesis of AD. It has(More)
Alzheimer's disease (AD) is a very common progressive neurodegenerative disorder. AD patients are affected by cognitive and memory deterioration. Cerebral degeneration, with selective neuronal death induced by extracellular amyloid deposits in the form of senile plaques and intracellular neurofibrillary tangles composed of helical paired tau protein, is the(More)
A proline-rich polypeptide complex (PRP) isolated from ovine colostrum shows immunoregulatory and procognitive activities. It shows beneficial effects in Alzheimer's disease (AD) patients when orally administered in the form of tablets called Colostrinin. The mechanism of action of PRP/Colostrinin in AD has not been yet clarified. It is known that oxidative(More)
The study aimed to assess the effect of the polypeptide Y complex (Yolkin), isolated from chicken egg yolk, on behavioural and cognitive functions. It also aimed to compare this activity with colostrum-derived substances (Colostrinin, Coloco), which have a confirmed impact on learning and memory. In the study, the effect of Yolkin, administered to rats of(More)
Neurotrophins such as nerve growth factor (NGF) and brain-derived neurotrophic factor, as well as cytokines, for example, interleukin-6 (IL-6) play an important role in neuroprotection and in the control of the central nervous system (CNS) function. Reduced expression of neurotrophic factors can lead to dysregulation of neuron function and neuronal death.(More)
The main elements of the central nervous system are the brain and the spinal cord. It contains millions of neurons and glial cells: astrocytes, oligodendrocytes, and microglia. The main role of the CNS is to process information, analyze signals, and activate effector organs. The role of the glial cells is the creation of the blood-brain barrier, the(More)
