Conversely to pathological findings, broadly HIV-1-neutralizing antibodies (BnAb) observed in several autoimmune diseases such as SLE, could exert a protective part against HIV infection. It is important to evaluate the onset of autoimmune diseases in HIV patients, in order to start the appropriate treatment to avoid harmful events. More studies are needed to enlighten the trend of autoimmune diseases during HIV infection. Pathogenic mechanisms and clinical manifestations of rheumatological diseases during HIV infection will be discussed in this review.Human interferon-stimulated gene 15 (ISG15) is a 15-kDa ubiquitin-like protein that can be detected as either free ISG15 or covalently associated with its target proteins through a process termed ISGylation. Interestingly, extracellular free ISG15 has been proposed as a cytokinelike protein, whereas ISGylation is a posttranslational modification. ISG15 is a small protein with implications in some biological processes and pathologies that include cancer. This review highlights the findings of both free ISG15 and protein ISGylation involved in several molecular pathways, emerging as central elements in some cancer types.Various neurodegenerative disorders have molecular origin but some common molecular mechanisms. In the current scenario, there are very few treatment regimens present for advanced neurodegenerative diseases. In this context, there is an urgent need for alternate options in the form of natural compounds with an ameliorating effect on patients. There have been individual scattered experiments trying to identify potential values of various intracellular metabolites. Purines and Pyrimidines, which are vital molecules governing various aspects of cellular biochemical reactions, have been long sought as crucial candidates for the same, but there are still many questions that go unanswered. Some critical functions of these molecules associated with neuromodulation activities have been identified. They are also known to play a role in foetal neurodevelopment, but there is a lacuna in understanding their mechanisms. In this review, we have tried to assemble and identify the importance of purines and pyrimidines, connecting them with the prevalence of neurodegenerative diseases. The leading cause of this class of diseases is protein misfolding and the formation of amyloids. A direct correlation between loss of balance in cellular homeostasis and amyloidosis is yet an unexplored area. Saracatinib price This review aims at bringing the current literature available under one umbrella serving as a foundation for further extensive research in this field of drug development in neurodegenerative diseases.Angina pectoris, associated with coronary artery disease, a cardiovascular disease where, pain is caused by adverse oxygen supply in myocardium, resulting in contractility and discomfort in chest. Inflammasomes, triggered by stimuli due to infection and cellular stress have identified to play a vital role in the progression of cardiovascular disorders and thus, causing various symptoms like angina pectoris. Nlrp3 inflammasome, a key contributor in the pathogenesis of angina pectoris, requires activation and primary signaling for the commencement of inflammation. Nlrp3 inflammasome elicit out an inflammatory response by emission of pro inflammatory cytokines by ROS (reactive oxygen species) production, mobilization of K+ efflux and Ca2+ and by activation of lysosome destabilization that eventually causes pyroptosis, a programmed cell death process. Thus, inflammasome are considered to be one of the factors involved in the progression of coronary artery diseases and have an intricate role in development of angina pectoris.Diabetic neuropathy is referred to as a subsequential and debilitating complication belonging to type 1 and type 2 diabetes mellitus. It is a heterogeneous group of disorders with a particularly complex pathophysiology and also includes multiple forms, ranging from normal discomfort to death. The evaluation of diabetic neuropathy is associated with hyperglycemic responses, resulting in an alteration in various metabolic pathways, including protein kinase C pathway, polyol pathway and hexosamine pathway in Schwann and glial cells of neurons. The essential source of neuronal destruction is analogous to these respective metabolic pathways, thus identified as potential therapeutic targets. These pathways regulating therapeutic medications may be used for diabetic neuropathy, however, only target specific drugs could have partial therapeutic activity. Various antidiabetic medications have been approved and marketed, which possess the therapeutic ability to control hyperglycemia and ameliorate the prevalence of dia of diabetic neuropathy.

In patients infected by HIV-1, some cellular biomarkers such as microRNAs have an important function in the suppression or progression of the disease. The aim of the current study is to evaluate the expression of mir-221, mir-29a, mir-155, and mir-146a in HIV-1 infected patients.

The miRNAs of 60 HIV-1 infected patients (sample group) and 20 healthy controls (normal group) were extracted from their peripheral mononuclear cells. We used TaqMan-based Real-time PCR for evaluation of expression mir-155,mir221, mir-29a and mir-146a by the comparative method. To evaluate differences among the data, one-way ANOVA was used. The expression of mir-155 andmir-146a in HIV-1 patients (sample group) was down-regulated in comparison with healthy controls (normal group) with a confidence value, (p <0.001). Also, in the sample group the expression of mir221 was downregulatedin compared to the normal group (p <0.001).

There was no significant difference in expression mi-29a in sample and control group. Inthe sample group, mir-221 hadlow expression and mir-29a had a high expression, respectively. According to the results of the current study and comparable studies, it seems that the microRNA has an important role in the progression or suppression of HIV-1 infection.

However, the data showed, besides others cellular and viral factor, we could use these miRNAs as a biomarker. However, the experts in themiRNAs field are in general agreement that more investigation is needed to use miRNAs as a biomarker in HIV.
