Results from a Trial of the Senolytic Fisetin in a Single Individual with Autoimmunity

Today's materials from the Intraclear Biologics team may be of interest to those following the development of senolytic therapies. Since the Mayo Clinic has yet to publish results from their clinical trials of fisetin as a senolytic therapy, and may not do so for a few years yet, it is good to see even preliminary data from other sources. Senolytic therapies selectively destroy senescent cells, though only one approach (the combination of dasatinib and quercetin) has been definitely shown to destroy significant numbers of senescent cells in humans. Data has yet to be published on whether fisetin performs as well in humans as it does in mice. The Intraclear Biologics data is an example of the Mayo Clinic's senolytic dose of fisetin applied to a single younger patient with autoimmunity - in effect a well-conducted self-experiment. The age of the patient, mid-thirties, is far too young to have any meaningful age-related accumulation of senescent cells. But various lines of work from recent years suggest that many autoimmune conditions are at least in part driven by the presence of senescent cells, a bidirectional dysfunctional relationship between the immune system and senescent cells in the tissue under attack. Type 1 diabetes, for example, and perhaps rheumatoid arthritis. Unfortunately, no assessment of senescent cell burden was carried out in this study, so it is possible that other mechanisms are involved in the lowered inflammation and other benefits experienced by ...

In this study, they found these drugs can kill senescent cells from cultures of human fat tissue. The tissue was donated by individuals with obesity who were known to have metabolic troubles. Without treatment, the human fat tissues induced metabolic problems in immune-deficient mice. After treatment with dasatinib and quercetin, the harmful effects of the fat tissue were almost eliminated. Targeting p21Cip1 highly expressing cells in adipose tissue alleviates insulin resistance in obesity Insulin resistance is a pathological state often associated with obesity, representing a major risk factor for type 2...

Introduction Alopecia areata (AA) is a common cause of immune-mediated non-scarring hair loss. Links between AA and common mental health, autoimmune and atopic conditions, and common infections have previously been described but remain incompletely elucidated and contemporary descriptions of the epidemiology of AA in the UK are lacking. Methods and analysis Retrospective study series using a large population-based cohort (5.2 million) from the Oxford Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) database, exploring four themes: AA epidemiology, mental health comorbidities, autoimmune...

ConclusionFamilial Mediterranean Fever could be associated with other autoimmune diseases such as Ankylosing Spondylitis, Rheumatoid Arthritis, Polyarteritis Nodosa, Behcet disease, Systemic Lupus, Henoch-Sch önlein Purpura, and Hashimoto’s Thyroiditis. Association of type 1 Diabetes Mellitus and Familial Mediterranean Fever has been newly reported in the medical literature, this is the third association of these two diseases described in the medical literature so far.

Conclusions1). Polymorphisms rs7138803-FAIM2 and rs1748033-PADI4 are more frequent in patients with autoimmune thyroid diseases, more frequent in patients with Hashimoto’ thyroiditis, but the occurrence of GG rs7138803-FAIM2 genotype could reduce the risk of thyrocyte apoptosis inhibition. 2). The TT rs7093069-IL2RA genotype may increase the risk of autoimmune thyroid diseases. 3). Analysis of polymorphisms of given genes in clinical practice will allow to determine predisposition to autoimmune thyroid disease development, to find symptoms of thyroid gland dysfunction earlier and to use appropriate treatment.

Abstract Objective: Autoimmune conditions tend to cluster in subjects with Addison's disease (AD) and probably also among their relatives. The aim of the study was to estimate the frequency of the endocrine gland-specific autoantibodies in first-degree relatives of patients with AD. Methods: Autoantibodies were investigated in 113 family members using RIA and ELISA assays. The control group comprised 143 age-matched volunteers. Results: Autoimmune diseases were diagnosed in 38.1% relatives. Hashimoto's thyroiditis was found in 20.3%, Graves' disease in 8.0%, vitiligo and type 1 diabetes in 3.5%, whereas ...

Conclusion: This study is the largest to date analyzing the potential influence of neighborhood deprivation on ADs. Our results indicate that neighborhood deprivation may affect risk of ADs, independent of individual level sociodemographic characteristics. For health care policies, both individual and neighborhood level approaches seem to be of importance.

If you or someone close to you have an autoimmune condition such as rheumatoid arthritis, lupus, Hashimoto’s thyroiditis, Crohn’s disease or ulcerative colitis, along with about 195 others, there are a number of steps you can take that reduce, even eliminate the autoimmune inflammation damaging your organs. (Unfortunately, some forms of autoimmune damage cannot be reversed. Autoimmune loss of pancreatic beta cells that lead to type 1 diabetes, Hashimoto’s thyroiditis that damages the thyroid gland, or autoimmune hepatitis that can lead to cirrhosis. for example, cannot be reversed even if the autoimmune p...

GD, and AT, can be associated with other organ specific, or systemic autoimmune diseases in the same patient. However discordant results have been reported in the literature about the possible associations. Here, we review...
