The human body’s functioning
The human body’s functioning is deeply dependent on the Central Nervous System, whose primary role is to ensure the transmission of nerve impulses to the effector organs for a response. The brain is one of the critical organs that coordinates body activities, including memory. However, some diseases such as Alzheimer’s Disease have adverse effects on the memory of the victim. Understanding the mechanism of nerve impulse transmission, particularly in the synapsis, forms the foundation of dealing with diseases that affect the brain, including Alzheimer’s Disease. Understanding the causative pathogen and treatment protocols should be accompanied by adequate knowledge of the infection mechanism. Further, treatment procedures won’t be effectively applied if the neurotransmitter substances’ interactions with the pathogen are not effectively-known. Amyloid β (A β), the pathogen responsible for Alzheimer’s Disease, achieves its purpose by degrading the excitatory transmission at the synapsis.
Overview of the Article
The current study’s purpose is to expound on the understanding of Alzheimer’s Disease by investigating the impact of acute A1-42 when applied on GABAergic synaptic transmission in rats. According to Ulrich (2015), Ab plays a crucial physiological role when present under normal conditions. However, it is transformed into a toxic substance that increases the influx of Calcium Ions into the synaptic cells leading to hyperexcitability. Further, the process leads to the loss of neurotransmitter glutamate. As revealed by the authors, the glutamate receptors’ loss aggregates to an adverse level, plasticity. The progressive loss of memory is associated with the decline in synaptic plasticity among Alzheimer’s patients.
Despite the availability of appreciable evidence for the AB-related pathophysiology at the glutamatergic synapsis, there exists non-consistent data for GABA, the primary inhibitory neurotransmitter substance present in the forebrain. Motivated by the desire to fill this gap, the current research found that the GABAergic inhibition in the rat models was upregulated. On the other hand, the GABAergic synaptic transmission was neither altered nor enhanced. The brain regions and the disease model being investigated significantly varied, and this could be a possible cause of the remarkable differences.
The visual observations made on the somatosensory cortex cells revealed that AB1-42 reduces the GABAergic transmission. This discovery has considerable contributions towards the improved treatment of the Disease. Further, the experiments revealed that AB1-42 leads to downregulated GABAergic receptors. According to, exocytosis and endocytosis have a significant role in effective synaptic inhibition. Equally, these findings add to the existing literature about Alzheimer’s disease and, consequently, strengthen the efforts to improve Alzheimer’s patients’ quality.
The novelty of the Results
The findings of this research have been derived from experiments using rat models. According to, rats are widely used as lab models to study diseases affecting human beings. Their wide use is based on the similar genital constitution between mice and human beings. The novelty of the findings is further increased by the authors experience in the clinical field. Being medical professionals have adequate knowledge of medical research. Notably, the experiments whose results have been discussed in this article were comprehensive. The use of various models of the disease and brain parts increases the scope of the research and consequently provides resources full results. The research has used various related research works that were conducted using primary sources of information, including experiments. The use of research articles containing novel results increases the novelty of the results. Finally, the researchers have declared a lack of conflicting interests in the research. Lack of conflicting interests in the research implies that it is free from biasness hence contains original findings of the experiments.
Outstanding Questions
What can appropriate physiotherapy practices be combined with other treatment procedures to deal with Alzheimer’s Disease effectively? According to Pelosin et al. (2018), the use of physiotherapy in treating Alzheimer’s disease has been neglected for a longer time. Pelosin et al. (2018), feel that physiotherapy practices can be combined with the medication protocol to help remedy the situation. However, the physiotherapy practices that can be effective in dealing with Alzheimer’s disease are not known. What can appropriate physiotherapy practices be combined with other treatment procedures to deal with Alzheimer’s Disease effectively?
Conclusion
Developing effective treatment of any disease is deeply dependent on detailed research work. The current research aims to establish the role played by AB in synaptic inhibition. The findings reveal a direct influence of the AB on synaptic inhibition. The results are novel considering the nature of sources utilized, primary sources. Further, the experiments conducted using the rat models have increased the novelty of the findings. Having novel findings increases the credibility and reliability of any research.
