integrated-peptides The study of reptilian peptides is an emerging field with significant implications for understanding innate immunity, drug discovery, and even human health. While the term "reptilian peptides" might evoke images of snake venom, research increasingly reveals a broader spectrum of these molecules across various reptile species, highlighting their diverse biological roles and potential therapeutic applications. These peptides, derived from diverse sources within reptiles, are being investigated for their potent antimicrobial properties and their unique signaling mechanisms, which may offer novel insights into processes relevant to human biology2017年8月24日—Furthermore, Pb-CATH4 possesses a completely different maturepeptidesequence from those of previously describedreptiliancathelicidins. These ....
A significant area of focus within reptilian peptide research is their role as antimicrobial peptides (AMPs)作者：CB Falcao·2014·被引用次数：96—These. Asian elapid (cobra)peptideswere up to now the only examples ofreptiliancathelicidins. Some clues about the presence of cathelicidins .... Reptiles, despite their ectothermic nature, exhibit remarkable resistance to infections, a trait largely attributed to their sophisticated innate immune systems. This resilience is partly mediated by a diverse array of AMPs, including defensins and cathelicidins, which are crucial for combating bacterial, fungal, and viral pathogens. Studies have identified specific reptilian defensins, such as reptilian β-defensins, and cathelicidin-related peptides like vipericidins, demonstrating their broad-spectrum antimicrobial activityAdvancing drug discovery with reptile and amphibian ....
The potential of these naturally occurring molecules for therapeutic use is a major driver of research. For instance, peptides derived from snake venom and other reptilian sources are being explored as novel antimicrobial agents. This is particularly relevant in an era of increasing antibiotic resistance, where new strategies are urgently needed.作者：ML van Hoek·2014·被引用次数：170—This paper will review the known (Table 1) and predicted antimicrobialpeptidesofreptiles. Recently, newreptiliangenomes have been sequenced ... The unique structures and mechanisms of action of these peptide compounds may offer advantages over conventional antibiotics, potentially overcoming existing resistance pathways.
While antimicrobial activity is a prominent feature, reptilian peptides are involved in a wider range of biological functions. Research has indicated that certain reptiles possess peptides that play a role in regulating growth hormone (GH) in ways distinct from mammals, suggesting evolutionary divergence in endocrine signalingReptilian β-defensins: Expanding the repertoire of known .... Furthermore, studies on the gut microbiome of reptiles have revealed the presence of novel molecules, including peptides, that can influence the host's epigenome, hinting at complex interkingdom interactions作者：WJ Krause·1997·被引用次数：33—We conclude that functional receptor-guanylyl cyclases and one or more endogenous guanylin/uroguanylin-likepeptidesoccur in the intestinal tract ofreptiles....
Another area of investigation involves peptides found in reptilian hemoglobin and those involved in signaling pathways within the intestinal tract.The present invention provides compositions useful as antimicrobial agents which includereptilianhemoglobin, the α and β chains of hemoglobin free of heme. For example, guanylin-like peptides in reptiles have been shown to stimulate cGMP accumulation in human intestinal cells, indicating a conserved signaling cascade with potential relevance for human physiology. The discovery of collagen peptides in historical contexts, possibly derived from tortoise shells or lizards, also points to the long-standing interaction between humans and reptiles, though this is more of a historical and material science observation rather than a direct biological link.
The exploration of reptilian peptides holds considerable promise for various applications.2016年2月4日—Previous in-vivo studies have isolated and identifiedpeptideswith typical molecular anti-microbial characteristics inreptiles. The identification of potent antimicrobial peptides from reptiles could lead to the development of new drugs and treatments for infectious diseases. Their unique evolutionary adaptations to combat pathogens make them valuable models for understanding innate immunity and for discovering novel therapeutic compounds.
Moreover, the study of reptilian peptides contributes to a broader understanding of molecular evolution and the diversity of biological molecules across species. By comparing reptilian peptides with their counterparts in other vertebrates, including humans, researchers can gain insights into conserved biological processes and species-specific adaptationsGenomewide Analysis of the Antimicrobial Peptides in Python ....
