Alzheimer’s disease (AD) remains one of the most challenging neurodegenerative disorders worldwide, characterized by progressive cognitive decline and memory impairment. Despite decades of research, therapeutic options are limited, and current treatments primarily provide symptomatic relief without effectively halting or reversing disease progression. A hallmark pathological feature of AD is the extracellular accumulation of amyloid-beta (Aβ) […]
Aging is a multifaceted biological process characterized by a progressive decline in physiological function and increased vulnerability to chronic diseases. At the cellular level, one of the key hallmarks of aging is the accumulation of senescent cells, which cease dividing but remain metabolically active. These senescent cells contribute to tissue dysfunction and chronic inflammation through […]
Aging is an intricate biological process characterized by the gradual decline in cellular and systemic functions, ultimately leading to increased susceptibility to diseases and mortality. Among the many molecular mechanisms proposed to drive aging, telomere attrition has emerged as a key hallmark. Telomeres, the repetitive nucleotide sequences capping chromosomal ends, safeguard genomic stability but shorten […]
Mitochondrial-derived peptides (MDPs) have recently attracted significant interest for their multifaceted roles in cellular homeostasis, metabolism, and aging. Among these, MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA-c) stands out as a novel bioactive peptide encoded by the mitochondrial genome that orchestrates systemic metabolic regulation. Discovered less than a decade ago, MOTS-c has rapidly […]
Copper peptides have long captured the attention of dermatologists and cosmetic chemists for their remarkable regenerative properties. Among them, GHK-Cu (glycyl-L-histidyl-L-lysine–copper) has emerged as a potent molecule with wide-ranging physiological benefits that extend far beyond aesthetics. Originally identified in human plasma in the 1970s, GHK-Cu is now being rigorously investigated for its role in wound […]
The global burden of type 2 diabetes mellitus (T2DM) continues to escalate, prompting intensive research into novel therapeutic strategies beyond traditional oral hypoglycemics and insulin therapies. Among these, peptide based treatments have emerged as a highly promising avenue, particularly glucagon like peptide 1 (GLP1) analogues, which harness the physiological role of incretin hormones in glycemic […]
In recent years, the therapeutic potential of synthetic peptides has garnered significant attention, particularly in the realms of neurology and psychiatry. Among these peptides, Semax and Selank stand out due to their unique neuroprotective properties and promising applications for cognitive enhancement and stress modulation. Originally developed in Russia for the treatment of neurological disorders, these […]
Reproductive endocrinology is a complex field governed by intricate hormonal signaling networks that coordinate the development and function of the reproductive system. Among the myriad peptides involved, kisspeptins have emerged as pivotal regulators of the hypothalamic-pituitary-gonadal (HPG) axis. Since their discovery in the early 2000s, kisspeptins have been recognized as critical neuropeptides modulating reproductive function […]
As the prevalence of neurodegenerative diseases continues to rise globally, the search for innovative therapeutic interventions has become increasingly urgent. Among the emerging candidates, Dihexa has garnered significant attention for its unique neurotrophic properties and cognitive-enhancing effects. Developed from angiotensin IV analogs, Dihexa exhibits the remarkable ability to promote synaptogenesis—positioning it as a potential game-changer […]
Sexual dysfunction remains a widespread and multifactorial clinical concern, affecting both men and women across diverse age groups. Traditional therapeutic approaches—such as phosphodiesterase type 5 (PDE5) inhibitors—primarily act on peripheral mechanisms by enhancing vascular response. However, they often fail to address the central neurological pathways involved in sexual desire and arousal. In recent years, PT-141 […]
