HtD is caused by the repetition of cytosine-adenine-guanine (CAG) in HtD gene, which further leads to the formation of a mutant Huntington (mHtt) protein that is responsible for neuronal dysfunction and cell death. Symptoms of HtD usually begin in adulthood and progress slowly, resulting in psychiatric disturbances, motor deficits and cognitive dysfunction. The medium spiny neurons of the striatum and cortex are mainly affected in HtD. Multiple hypotheses have been proposed to elucidate the underlying mechanisms that lead to neuronal dysfunction and cell death. This typically includes molecular genetics, oxidative stress (OS), excitotoxicity, mitochondrial impairment etc. Natural bioactives are a diverse group of compounds derived from plants, animals and microorganisms. They have been found to modulate multiple signaling pathways involved in the development of HtD and have potentials in reducing OS, neuroinflammation, and neuronal death, which are key pathological processes in HtD.Mostly natural bioactive offers protection either by down-regulating the OS, excitotoxicity, mitochondrial dysfunctions, microglial inactivation<strong>,</strong> neuroinflammation and/or by upregulating ubiquitin-proteasome system, autophagy &amp; lysosomal degradation pathway, apoptotic pathway, purinergic signaling pathway.In this chapter, we have summarized various natural bioactives that exhibit therapeutic potential against HtD.

While conventional pharmacological treatments, though valuable, usually fall short in addressing their multifaceted nature, the pursuit of innovative solutions has led to the exploration of ayahuasca, a psychedelic brew originating from Amazonian plants, as a promising candidate. Recent investigations have unveiled its therapeutic potential in psychiatric disorders, particularly depression, characterized by notable alterations in mood-regulatory brain networks. In this narrative review, we explore ayahuasca's potential role in modulating neuropathic pain. Through the analysis of preclinical studies and functional MRI analyses, we aim to elucidate its influence on the affective-motivational component of pain perception and the complex immune modulation intrinsic to the pathophysiology of NP. Ayahuasca demonstrates the capacity to reduce activity within regions of the default mode network, closely linked with depression, thereby presenting a novel approach to addressing the interwoven complexities of chronic pain and mood disturbances. Furthermore, its potential to activate serotonin and sigma-1 receptors and modulate the immune/inflammatory response, including glial cells and the midbrain periaqueductal gray, a pivotal brain structure in the propagation and modulation of pain, provides valuable insights into its analgesic mechanisms.

This study delves into these complexities by comparing the immunological landscapes of healthy individuals from distinct backgrounds: 40 Vietnamese and 24 German participants. Our comprehensive analysis, encompassing 42 lymphocyte populations and 17 cytokines, reveals profound differences in immune profiles between these two populations. Utilizing multicolor flow cytometry and advanced analytical platforms, we conducted a comprehensive characterization of the cellular and molecular components of individual immune systems. Statistical analyses revealed highly significant differences (p &lt; 0.05) between Vietnamese and German cohorts in 33 out of 42 lymphocyte populations and 15 out of 17 cytokines. These disparities encompassed a wide range of immune cell subsets, including T, B and NK cells and involved both activating and inhibitory immune regulators. Healthy Vietnamese subjects exhibited significantly higher numbers of B, T and NK cells compared to their German counterparts. Vietnamese participants displayed higher proportions of plasma cells, immature B cells, and B cells with low CD21 expression (CD21low), which have a phenotypic characteristic of chronic stimulation. Of the 16 subpopulations of CD4+ and CD8+ T cell subpopulations, 11 were significantly elevated in Vietnamese compared to German subjects. Additionally, Vietnamese participants expressed higher proportions of markers for functional and activating NK receptors, indicating the presence of highly cytotoxic NK cells in this population. Almost all of the 17 cytokines examined were significantly lower in Vietnamese subjects. These results demonstrate statistically significant variations in immunological profiles between healthy individuals from Eastern and Western populations. Our findings suggest that caution should be exercised when applying Western reference health profiles to Eastern subjects in clinical settings.
