Communication between Brain and Non Brain organ cells.

 For the decades the Researchers making the debate around the Communication between Brain and non Brain cells. , we have searched so many methods that the cells are interacting With the Body or organs nom Brain cells. this cells are sending signals to organ Cells about the feel, pain, heat and cold. But in this Communication, whether the non Brain cells acts as a memory storage about the facts or how to heal any disease as per the timing frame given so on.

Nerve cells (also known as neurons) utilize a combination of electrical and chemical signals for communication. While electrical signals induced by charged particles are confined to the neuron, the neuron can quickly conduct that signal from one end of the neuron to the other. When nerves communicate with one another, they communicate across tiny gaps called synapses, in which the specialized parts of the two neurons (the presynaptic neuron and the postsynaptic neuron) get within nanometers of one another in order to communicate chemically. The presynaptic neuron releases a chemical (known as a neurotransmitter), which the postsynaptic neuron receives through its specialized proteins called the neurotransmitter receptors. 

The neurotransmitter molecules bind to the receptor proteins and cause the postsynaptic neuron to alter neuron function. There are two types of neurotransmitter receptors -- ligand-gated ion channels that provide rapid ion flow directly through the outer membrane of the cell and G-protein–coupled receptors that initiate chemical signaling processes inside the cell. Hundreds of molecules are considered to be neurotransmitters in the brain. Neuronal development and function are also influenced by peptides called neurotrophins and by steroid hormones.

   we can categorize here that how the non. Brain cells can adapt the interactions with the Brain cells and how the method can take place in the form of self healing procedures in cases of mild disease or certain treatable infections

we have summarized with the several points.  

1. Brain cells release the neurotransmitter in the form of signals to communicate with the other cells.   

 2. In case of any infection. the signals. send to Brain and the memory.Examples of this communication include sensory neurons relaying information from the body to the brain, motor neurons carrying instructions from the brain to muscles, and the vagus nerve transmitting signals about organ function. 

3. Pain, swelling, or redness associated with throat infections communicate with the brain through sensory neurons. After analyzing this data, the brain sets off inflammatory reactions such as fever (to raise body temperature and kill the pathogens) or systemic fatigue (to save energy). The cough reflex, which helps remove pathogens from the respiratory system, may also be mediated by motor neurons. The vagus nerve may be triggered if the infection affects the stomach or heart.

Reasons for the Communication between the cells shown in detailed structure.

1. Analyze connections between brain and body

The human body has the ability to detect changes inside itself called interoception, a function that is essential for survival. Signals from the body to the brain are funneled through the vagus nerve, and the signals received by that nerve are coded separately by vagal sensory neurons.

"This is the first time we really understand how different signals from the body are represented in the vagal interoception system to the brain, and how this occurs in a very distinct and describable manner," Chang said. "We know that the brain can discriminate signals with great specificity, but what is the biological basis of this discrimination.

The brain receives signals from sensory neurons in the throat that tell the brain that infection is present (i.e., pain, swelling, redness). After the brain interprets this information, it activates inflammatory reactions like fever (increasing body temperature to kill pathogens), or generalized extreme fatigue (conserve energy). The brain activated the cough reflex to help expel the pathogen from the respiratory system, potentially through motor neurons. If the infection involves internal organs, like in the case of the heart or stomach, the vagus nerve may be activated.

2. EV-mediated Bidirectional Communication Between the Brain and Other Organs

The communication from the brain to other organs and vice versa is considered to occur via EVs. EVs can traverse the blood-brain barrier (BBB) to delivery lipids, peptides, proteins, and nucleic acids and can access and reach almost all organs. It is not easy to co-relate the source of EVs. As far as I am aware, brain-specific EVs have not yet been identified. However, like we have discussed earlier, telling the levels and their potential carriers of EVs is different under different physiopathological conditions. Since the contents of EVs depend on the parent cell state, it might be more manageable to clarify its origin with respect to a pathological condition. Astrocytic EVs revealed large quantities of complement that is associated with Alzheimer's disease (AD) and the levels of circulating neuronal EVs had high quantities of tau and β-amyloid protein (Aβ), which could open the door to their use as liquid biopsies for neurologic disorders.

3. Brain Communication: Influencing Thought and Behavior

Brain communication consists of complex networks of neurons that can autonomously rewire themselves, a process called neural plasticity. When we learn something new or develop a memory, neural rewiring circumvents a range of options. Neurons strengthen and weaken synaptic connections, according to dynamic activity. Neural rewiring provides an excellent basis for learning, adapting, and recovery from injuries. In addition to structural plasticity, electrical patterns (brain waves) coordinate activities in distant areas of the human brain, just as a symphony conductor directs the orchestra. Brain waves, or oscillations occur at varying frequencies, such as alpha and beta or gamma waves. These waves play a critical role in attention, sleep, and decision-making. Fast wave oscillations generally signify alertness or sensory engagement, while slower waves indicate relaxation and/or deep sleep. The structure of patterns facilitates integration of sensory input, internal state, and motor action.

4. Neural plasticity : The brain's amazing ability to rewire neurons' structures in response to both internal and external stimuli is known as neural plasticity. Numerous outside stimuli, sometimes known as "epigenetic factors," have the ability to promote neural plasticity. DNA methylation and methylation (as well as histone acetylation and deacetylation) are among the earliest types of epigenetic mechanisms underlying neural plasticity. Epigenetic signature molecules, primarily proteins, are essential to the process of epigenetic reprogramming and are responsible for any observed epigenetic changes. Although neuro-epigenetics is a fascinating new field, more research is needed to fully understand the crucial roles that signature proteins play in epigenetic change and neural plasticity.

Conclusion : The communication between the brain and non-brain organ cells is a well-coordinated, dynamic, complex process that is the basis of body function and health. The brain regulates and maintains homeostasis throughout the body via the central nervous system (CNS) and peripheral nervous system (PNS), and there is communication via immune system mediators as well. The brain can influence immune responses and immune cells can also provide signals to the brain.
