We studied the basic indicators of immune status of healthy persons of different age groups living in the monsoon climate in the southern Far East. The analysis shows age-dependent development of immunodepressive status, combined with increasing levels of CD16, CD25 and HLA-DR in the aging organism. Climatic and anthropogenic factors effect profoundly damaging on the body, which results in the severity of disorders of the immune system in old, old age and longevity.

How adult tissue stem and niche cells respond to the nutritional state of an organism is not well understood. Here we find that Paneth cells, a key constituent of the mammalian intestinal stem-cell (ISC) niche, augment stem-cell function in response to calorie restriction. Calorie restriction acts by reducing mechanistic target of rapamycin complex 1 (mTORC1) signalling in Paneth cells, and the ISC-enhancing effects of calorie restriction can be mimicked by rapamycin.

Bacopa monnieri (L.), popularly known as Brahmi, is a revered Ayurvedic medicinal plant used as nerve tonic since time immemorial. The present study aims to investigate the neuroprotective effect of bacosides, the active saponins of Bacopa monnieri (L.) against age associated neurodegeneration and its impact over the prevention of Senile Dementia of Alzheimer's Type (SDAT).

CONTEXT. Brassica juncea (BJ; Linnaeus) Czern & Coss (Brassicaceae), commonly known as Indian mustard, are enriched in redox-active polyphenols with antidiabetic activities. Diverse other health benefits of this edible plant have been described in classical Ayurvedic texts. OBJECTIVE: The reported experiments were designed to assess therapeutic potential of a methanol extract of BJ leaves for treatment of cognitive disorders associated with diabetes or caused by central cholinergic dysfunctions.

Gene

The inducible IkappaB kinase (IKKi/IKKepsilon) is a recently described serine-threonine kinase that activates the transcription factors NFkappaB, interferon regulatory factor-3 (IRF3) and CCAAA/enhancer-binding protein (C/EBPdelta). Several inflammatory agents have been shown to induce the expression of the IKKi gene in macrophages and other cell types but the mechanism is unknown.

Given the high fatality rate of pancreatic cancer, an effective treatment for this devastating disease is urgently needed. We have shown that mesothelin expression was higher in human pancreatic cancer cells than in human pancreatic duct epithelial cells, and mesothelin mRNA was substantially overexpressed in 18 of 21 (86%) clinical pancreatic adenocarcinoma specimens when compared with the surrounding normal tissues. However, the biological functions of mesothelin in tumor progression are not clearly understood.

Mesothelin (MSLN) is a cell surface glycoprotein that is overexpressed in human pancreatic cancer. Although its value as a tumor marker for diagnosis and prognosis and as a preferred target of immunointervention has been evaluated, there is little information on the growth advantage of MSLN on tumor cells.

BACKGROUND: A subset of CD3(neg)CD56(neg)CD16⁺ Natural Killer (NK) cells is highly expanded during chronic HIV-1 infection. The role of this subset in HIV-1 pathogenesis remains unclear. The lack of NK cell lineage-specific markers has complicated the study of minor NK cell subpopulations. RESULTS: Using CD7 as an additional NK cell marker, we found that CD3(neg)CD56(neg)CD16⁺ cells are a heterogeneous population comprised of CD7⁺ NK cells and CD7(neg) non-classical myeloid cells. CD7⁺CD56(neg)CD16⁺ NK cells are significantly expanded in HIV-1 infection.
