Background: The cachexia anorexia syndrome is a complex metabolic syndrome associated with cancer and some other palliative conditions characterized by involuntary weight loss involving fat and muscle, weight loss, anorexia, early satiety, fatigue, weakness due to shifts in metabolism caused by tumour by-products and cytokines. Various neuropeptides like Leptin, neuropeptide Y, melanocortin, agouti-related peptides have been known to regulate appetite and body weight.

Method: A comprehensive literature search was carried out on the websites of Pubmed Central (http://www.pubmedcentral.nih.gov/), National Library of Medicine (http://www.ncbl.nlm.nih.gov) and various other net resources.

Result: Data from observational studies shows that various cytokines (TNF-α, IL-6 and IL-1) are associated with metabolic changes resulting in cachexia in cancer patients. These cytokines may mimic the action of various neuropeptides resulting in anorexia, various metabolic effects resulting from enhanced catabolic state and weight loss.

Conclusion: There is a need to understand and explore the role of various neuropeptides and cytokines in the pathophysiology of cancer-anorexia syndrome so that therapeutic measures may be designed for effective palliative care.

Sleep is the most important physiological function of all animals studied to date. Sleep disorders include narcolepsy, which is characterized by excessive daytime sleepiness, disruption of night sleep, and muscle weakness-cataplexy. Narcolepsy is known to be caused by the degeneration of orexin-synthesizing neurons (hypocretin (HCRT) neurons or orexin neurons) in the hypothalamus.

Parkinson's disease (PD) is a neurological condition and is characterized by both motor and non-motor symptoms. Early diagnosis is essential for effective therapy and management; nevertheless, present diagnostic methods are frequently insufficient and primarily rely on clinical symptoms that appear later in the disease. Neuropeptides, such as alpha-synuclein (α-syn), Substance P (SP), neurotensin (Nts), Neuropeptide Y (NPY), and somatostatin (SST), exhibit significant potential as biomarkers for the early identification of Parkinson's disease (PD).

Agouti-related peptide (AgRP) is a well-established potent orexigenic peptide primarily expressed in hypothalamic neurons. Nevertheless, the expression and functional significance of extrahypothalamic AgRP remain poorly understood. In this study, utilizing histological and molecular biology techniques, we have identified a significant expression of Agrp mRNA and AgRP peptide production in glomus type I cells within the mouse carotid body (CB).

Severe trauma frequently leads to nerve damage. Peripheral nerves possess a degree of regenerative ability, and actively promoting their recovery can help restore the sensory and functional capacities of tissues. The neuropeptide calcitonin gene-related peptide (CGRP) is believed to regulate the repair of injured peripheral nerves, with neuronal transient receptor potential vanilloid type 1 (TRPV1) potentially serving as a crucial upstream factor.

Dry eye disease (DED) is an inflammatory disorder in which CD4 T cells play a significant role in its pathogenesis. A CD4 T cell subset termed granulocyte-macrophage colony-stimulating factor-producing T helper (ThGM) cells would contribute to DED pathogenesis. However, the mechanisms by which the activity of ThGM cells is modulated are not thoroughly understood.
