Background: Systemic lupus erythematosus (SLE) is a complex autoimmune disease recognized by elevated activity of autoimmune cells, loss of tolerance, and decreased regulatory T cells producing inhibitory cytokines. Despite many efforts, the definitive treatment for lupus has not been fully understood. Curcumin (CUR) and berberine (BBR) have significant immunomodulatory roles and anti-inflammatory properties that have been demonstrated in various studies.

Basically, obesity, type 2 diabetes, and other related diseases, and cancer are associated with a common hyperactivated "lipogenic state." Recent evidence suggests that metabolic reprogramming and overproduction of enzymes involved in the synthesis of fatty acids are the new hallmarks of cancer, which occur in an early phase of tumorigenesis.

Familial hypercholesterolemia (FH) is the most common inherited form of dyslipidemia and a major cause of premature cardiovascular disease. Management of FH mainly relies on the efficiency of treatments that reduce plasma low-density lipoprotein (LDL) cholesterol (LDL-C) concentrations. MicroRNAs (miRs) have been suggested as emerging regulators of plasma LDL-C concentrations.
View Article and Find Full Text PDFAlthough a selective strong elevation in the plasma level of low-density lipoprotein (LDL) cholesterol is the hallmark of familial hypercholesterolemia (FH), also other plasma lipoprotein and lipid subspecies are changed in these patients. Several studies in FH patients have pointed to the qualitative abnormalities of high-density lipoprotein (HDL) particles, including their triglyceride and sphingomyelin enrichment, reduced capacity to promote cholesterol efflux from macrophages, impaired anti-inflammatory and anti-oxidant activities, and reduced plasma levels of miRs regulating HDL-dependent cholesterol efflux from macrophage foam cells, typical of atherosclerotic lesions. Thus, accurate understanding of HDL functionality and its disturbances in FH may serve a better estimation of the prognosis and also provide additional clues when searching for novel therapeutic choices in this disease.

Curcumin has been shown to exert pleiotropic effects by modulating different signaling molecules, including transcription factors, chemokines, cytokines, and adipokines. Disturbed regulation of adipokines, which include adiponectin, leptin, resistin, and visfatin, are implicated in the development of insulin resistance and Type 2 diabetes.

Inhibition of PCSK9 using monoclonal antibodies can efficiently lower plasma LDL-C, non-high-density lipoprotein cholesterol and lipoprotein (a). PCSK9 inhibition is also an effective adjunct to statin therapy; however, the cost-effectiveness of currently available PCSK9 inhibitors is under question.

In this review, we describe functional roles of well-known GC-modulatory cytokines, highlight the functions of cytokines with more recently described roles in GC, and emphasize the therapeutic potential of targeting the complex cytokine milieu. We also focus on the role of Helicobacter pylori (HP)-induced inflammation in GC and discuss how HP-induced chronic inflammation can lead to the induction of stem cell hyperplasia, morphological changes in gastric mucosa and GC development.

Inhibitors of proprotein convertase subtilisin/kexin type 9 (PCSK9) have emerged as effective low-density lipoprotein cholesterol-lowering compounds. Although the results of available epidemiological, preclinical, and clinical studies suggest a positive association of plasma PCSK9 levels with glycemic parameters and risk of type 2 DM (T2DM), genetic findings have shown contradictory results.

Novel animal and human studies indicate that curcumin can affect different immune cells, such as various T lymphocyte subsets, macrophages, dendritic cells, B lymphocytes and natural killer cells, which results in decreasing severity of various diseases with immunological etiology. The present review provides a comprehensive overview of the effects of curcumin on different immune cells and immune system-related diseases.

Moreover, the usage of cisplatin, a platinum-based chemotherapeutic, is associated with several adverse effects affecting the quality of life of the patients. Also, cisplatin therapy is jeopardized by a great challenge of resistance which reduces the efficacy of this drug.

The research on stationary and circulating CSCs due to resistance to conventional therapies and inability in complete eradication of cancer is critical for developing novel therapeutic strategies for a more effective reduction in the risk of tumor metastasis and cancer recurrence. This review compiles information about different methods of detection and dissociation, side population, cellular markers, and establishment culture of CSCs, as well as characteristics of CSCs such as tumorigenicity, and signaling pathways associated with self-renewal and the capability of the same histological tumor regeneration in various cancers.

There is growing evidence supporting the immunomodulatory ability of some probiotics. Several experimental and clinical studies have been shown beneficial effect of some probiotic bacteria, particularly Lactobacillus and Bifidobacteria strains, on inflammatory and autoimmune diseases.

Anti-inflammatory and antioxidant properties of curcumin, along with its immunomodulatory, proapoptotic, and antiangiogenic properties, are often referred to as the main mechanisms underlying the anti-tumor effects. At the molecular level, inhibition of NF-kB, Akt/PI3K, and MAPK pathways and enhancement of p53 are among the most important anticancer alterations induced by curcumin.
