Neuron cell Neural peptides, also widely known as neuropeptides, are fundamental to understanding how our complex nervous system functions作者：YL Tsai·被引用次数：7—Synthetic peptides provide a promising approach for neural repair, either as soluble drugs or by using their intrinsic self-assembly propensity .... These fascinating molecules are essentially chemical messengers made up of small chains of amino acids, acting as crucial communication links between neurons. Unlike smaller neurotransmitters, neuropeptides are typically sequences of amino acids, longer than classical neurotransmitters but shorter than full-sized proteins, and are often referred to as small protein-like molecules (peptides) used by neurons to transmit signals.Brain-gut Axis and Pentadecapeptide BPC 157 - PubMed Central - NIH Their intricate roles extend to modulating a vast array of physiological and behavioral processes, impacting everything from mood and pain perception to motor control and learning.

At their core, neuropeptides are synthesized and released by neurons, playing a vital role in neurotransmission. They are found in many mammalian CNS neurons, where they are instrumental in modulating neuronal activity.作者：F Gelain·2006·被引用次数：780—Here we report the development of a 3-D cell culture system using a designerpeptidenanofiber scaffold with mouse adultneuralstem cells. This modulation can occur in several ways, including influencing the release of other neurotransmitters, altering the sensitivity of neuronal receptors, and even changing the very structure of neural circuits over time. The precise action of a peptide is influenced by its specific amino acid sequence and the receptors it binds to on target cells.

One area where neural peptides have demonstrated remarkable influence is in the realm of tissue repair and regeneration. Research has indicated that certain neural peptides can promote significant biological processes. For example, the αCGRP-YAP pathway promotes angiogenesis and osteogenesis – the formation of new blood vessels and bone tissue – particularly during the early stages of bone healing. This suggests a potential for neural peptide-based therapies to accelerate recovery from bone injuries and fractures. Furthermore, studies have shown that a neural peptide regulates osseointegration of dental implants, a critical factor in the success of these devices. This highlights the broad applicability of peptides in regenerative medicine.

The therapeutic potential of peptides is being further explored through advancements in computational biology and artificial intelligence. For instance, the development of PepGB, a deep learning framework, aims to facilitate early peptide drug discovery by predicting peptide-protein interactions. Similarly, Recurrent Neural Network Model for Constructive Peptide Design, and specifically a generative long-term short-term memory (LSTM) recurrent neural network, are being utilized to design novel peptides with specific properties. This area of research is continuously evolving, leading to sophisticated tools like TP-LMMSG: a peptide prediction graph neural network that incorporates flexible amino acid property representation. The ambition is to create synthetic peptides provide a promising approach for neural repair, either by administering them as soluble drugs or by leveraging their inherent self-assembly capabilities into functional structures.作者：Y Lei·2024·被引用次数：4—In this study, we proposePepGB, a deep learning framework to facilitate peptide early drug discovery by predicting peptide-protein interactions (PepPIs).

Beyond their role in tissue repair, neuropeptides are intimately involved in the intricate communication between the brain and the gut, forming the brain-gut axis. This bidirectional communication pathway influences a wide range of functions, including digestion, mood, and even cognitive processes. The brain-gut axis and pentadecapeptide BPC 157 is an area of active investigation, with implications for gastrointestinal health and neurological function.
