Project description:In almost every countries the proportion of people over 60 years is growing faster that any other age group. Increased life expectancy is leading to the characterization of specific aspects of aging for the various physiological systems. The study of healthy aging is important to design strategies capable to maximize the health and to prevent chronic diseases in older people. Immunosenscence reflects the age-related changes of the immune system and the reduced capacity of elderly people to cope with new infections. To elucidate changes in gene expression related to systemic aging and immunosenescence in an unbiased manner we performed comparative microarray analysis on whole blood cell from healthy middle-aged versus elderly men, and correlated results with functional measurements of aerobic capacity. Blood cells from elderly subjects showed age-related changes in the expression of several markers of immunosenescence, inflammation and oxidative stress, and showed impairments in metabolic and biosynthetic capacities. Whole blood samples from twenty healthy men between the ages of 45-55 (n=11) and 65-75 (n=9) years old were analyzed for this study. For each subject blood was sampled in two different occasions, which were separated by at least 7 days. To preseve RNA quality and integrity 3 ml of blood have been collected intoTEMPUS Blood RNA tubes (ABI, Foster City, CA, USA). Total RNA has been depleted of globin mRNA using the GLOBINclearâ¢-Human kit (Ambion, Austin, TX). To reduce variations due to confounding events, such as spontaneous up- and down-regulation of genes, the two samples of clean RNA from each subject were pooled into one single sample (1ug+1ug RNA).

Project description:Differences in the activity of monocytes/macrophages, important target cells of Mycobacterium tuberculosis, might influence tuberculosis progression. With the purpose of identifying candidate genes for tuberculosis susceptibility we infected with M. tuberculosis monocytes from both, healthy elders (a tuberculosis susceptibility group) and elderly tuberculosis patients, and performed a microarray experiment. We detected 78 differentially expressed transcripts and confirmed these results by quantitative PCR of selected genes. We found that monocytes from tuberculosis patients showed similar expression patterns of these genes regardless of whether they were obtained from younger or elder patients. Only one of the detected genes corresponded to a cytokine: IL-26, a member of the IL-10 cytokine family that we found downregulated in infected monocytes from tuberculosis patients. We have analyzed total RNA from Mycobacterium tuberculosis infected monocytes. We have isolated CD14+ cells (monocytes) from peripheral blood mononuclear cells by magnetic separation, and infected them for 4 days with 1 bacterium per monocyte. Blood donors were 7 elderly patients with pulmonary tuberculosis (average age: 83 years; sex: 3 men and 4 women) and 8 non-tuberculous volunteers (81 years, 6 men and 2 women).

Project description:Due to multifactorial reasons, such as decreased thirst and decreased total body water, elderly patients are vulnerable to dehydration. The study aims to investigate whether moderate dehydration or hyperhydration affects the blood proteome. Blood samples, medication and bioelectrical impedance analysis (BIA) details were collected from 131 geriatric patients (77 women, 54 men). Based on an evaluation by Bioelectrical Impedance Vector Analyses (BIVA) of this cohort, for each hydration status (dehydrated, hyperhydrated and control), five appropriate blood serum samples for both male and female were analyzed by LC-MS. Overall, 262 proteins for female patients and 293 proteins for male patients could be quantified. 38 proteins had significantly different abundance, showing that hydration status does indeed affect the serum proteome. Protein enrichment analysis of the affected proteins revealed “Wound Healing” and “Keratinization” as the two main biological processes being dysregulated. Especially, proteins involved in clot formation are affected by hydration status.

Project description:Background: Hypertension is one of the most common metabolic diseases in the elderly and its pathogenesis is associated with microbiota dysbiosis. Recent evidence suggests that oral microbiota dysbiosis is also an important factor in the development of hypertension. However, the relationship between hypertension and oral flora in the elderly has not been adequately investigated. Objective: The aim of this cross-sectional study was to investigate the structure of the oral microbiota and its correlation with hypertension in elderly hypertensive patients. To provide new ideas for the prevention and treatment of hypertension. Methods: 206 subjects aged 60 ~ 89 years were selected and divided into normal (CON) and hypertensive (HTN) groups, according to the 2018 Chinese Guidelines for the Management of Hypertension. The oral microbiome composition of saliva samples was determined by 16S rRNA gene sequencing. Results: Although there was no significant difference in α and β diversity between the two groups, systolic and diastolic blood pressure were the most important factors influencing the structure of the oral microbiota. At the phylum level, the relative abundance of the spirochete phylum and the mutualistic bacterial phylum was higher in the HT group than in the CON group (p < 0.05). Diastolic blood pressure was negatively correlated with Streptococcus. Furthermore, we analyzed HTN patients with 120 mmHg<systolic blood pressure<160 mmHg and systolic blood pressure>160 mmHg separately and found that the abundance of Saccharibacteria_(TM7) was significantly increased in the HTN_2 group. Conclusions: Our study identified specific oral microbiota in elderly hypertensive patients, confirming the relationship between oral microbiota and hypertension. This enhances our understanding of the important role of oral microbiota in the pathogenesis of hypertension and accumulates more evidence for microbial involvement in the development of hypertension.
