Activity in vagal fibers results in increased transmission of cholinergic ligands onto the cholinergic receptors on macrophages, mediated by the splenic nerve, subsequently reducing cytokine production (Wang H. et al., 2003; Rosas-Ballina et al., 2008). A new promising staining method called GL13 was recently proposed based on detection of lipofuscin using an analog of Sudan Black B histochemical dye coupled with biotin (Evangelou et al., 2017). The model is currently based on converging and correlational evidence; however, longitudinal designs are needed. Aging is in fact a primary risk factor for many diseases and in … Conversion of psychological stress into cellular stress response: Roles of the sigma-1 receptor in the process.

H2O2 damaged DNA triggers a cell death signaling via a pathway called the mitogen activated protein kinase (MAPK) Jun N-terminal kinase (JNK; MAPK JNK) pathway, a mechanism for apoptotic prevention of gene mutations and further damage (Dhanasekaran and Reddy, 2008). Stress 20, 249–257. This method is potentially more sensitive than SA-β-Gal staining due to the biotin coupling allowing it to be detected using anti-biotin antibodies and identified using both microscopy and flow cytometry (Evangelou et al., 2017), although the potential for detecting false positives has not been completely abolished (Salmonowicz and Passos, 2017).

Senescent cells are hard to detect for several reasons: several of the genetic changes that occurs in cells undergoing senescence is not exclusive to senescent cells; senescence is a multifactorial process with phenotypic changes occurring at different times; the phenotypic profile of senescent cells varies according to stimuli and cell type, and; senescent cells have different roles that varies according to physiological context (van Deursen, 2014). doi: 10.1111/j.1749-6632.2009.04414.x, Epel, E.

Detection of senescent cells by extracellular markers using a flow cytometry-based approach. Telomerase activity was related to greater hemodynamic arousal, lower vagal tone, and greater sympathetic reactivity to the acute mental stressor. Astrocytes treated with TNF-α also show an upregulation of p38MAPK (Thompson and Van Eldik, 2009) which contributes to the upregulation of SASP factors in cellular senescence (Coppé et al., 2008; Freund et al., 2010).

This might have several implications for telomerase activity; since NFκB upregulates telomerase (Ghosh et al., 2012) and both ROS and TNF-α can suppress telomerase activity (Houben et al., 2008; Deeb et al., 2013), then the effect of vagal activity on telomerase activity might depend on degree of NFκB activation. doi: 10.1523/JNEUROSCI.5587-06.2007, Segerstrom, S.

Several mechanisms have been proposed for how psychological stress could be converted into cellular stress (Hayashi, 2014), including the production of pro-inflammatory cytokines and reactive oxygen species, both antecedents to events that can initiate the senescence response (Campisi, 2001, 2003). 7, 69–87.

Once the p53 protein is activated it initiates a transcriptional program that reflects the stress signal, the protein modifications and the proteins associated with the p53 protein. Ageing - a universal finding in humans - is the leading risk factor for deterioration of structure and function of tissues and organs in most of the chronic conditions that limit lifespan and quality of life [].As compared to the general population, patients with chronic kidney disease (CKD) have a much accelerated ageing process characterized by progressive vascular disease, … 29, 72–79. doi: 10.1073/pnas.1322145111, Zeevi, N., Pachter, J., McCullough, L.

Examinations of post-meditation cellular activity revealed a downregulation of NFκB activation in participants in addition to the reported upregulation of telomerase activity (Bhasin et al., 2013), contradictory to more recent findings, reporting no decrease in NFκB specifically, but suppressions in large inflammatory gene networks in their regular meditator group, and an increase in TNF-α in their vacation group post retreat (Epel et al., 2016). Nat. Neurosurg. Increased reactive oxygen species due to reduced capacity to regulate psychological stress cause oxidative telomere damage (Zalli et al., 2013; Streltsova et al., 2017) resulting in cellular senescence (Campisi, 2001, 2003). Commun. Basic Clin. Thus, being an indicator of PNS activity and a proxy for prefrontal activation, higher vagally mediated HRV is related to fine-grained control over arousal during prolonged stressors (Hildebrandt et al., 2016) expressed as a stress resilient mode of coping and recovery. Cortisol and adrenaline but not vagal tone was found to be associated with telomere length (Epel et al., 2006).

Further corroboration of the link between stress reduction techniques and telomere integrity was reported in a study that compared expert meditators to matched controls, where expert meditators had significantly longer mean telomere length, and a lower percentage of short telomeres in individual cells compared to the comparison group (Alda et al., 2016). PNS inhibition remains dominant at rest and maintains a resting heart rate that is below the intrinsic firing rate of the heart. 1989 – European Championship (5th place) 1990 – World League (5th place) 1990 – World Championship (8th place) … Infect.
