Curcumin-Like Compounds as Neuroprotective Agents: Interactions with HSP60 and Amyloid Beta Peptide

2014

Alzheimer’s Disease (AD) represents a fundamental challenge for public health in the 21st century. Current AD therapies largely focus on symptomatic aspects of the clinical pathology, but they have yet to demonstrate any major impact on the disease progression [1]. The most important role of the research aimed at fighting the AD is the development of neuro-protective agents, able to interfere with the protein aggregation process whose clinical signature is represented by the plaques deposition. An important role in AD’s framework could be played by Heat shock proteins (HSPs), highly regulated proteins that mediate the proteins proper folding and promote recovery of their native conformation…

Chaperonin Hsp60 and Cancer Therapies

2020

The heat shock protein 60 (Hsp60) is a chaperonin belonging to the chaperoning (chaperone) system that typically contributes to protein homeostasis inside mitochondria, but also plays various non-canonical roles unrelated to protein quality control beyond the organelle. Chaperonopathies are disorders in which chaperones play an etiologic-pathogenic role and contribute to the onset/progression of disease. Hsp60 chaperonopathies by mistake are diseases in which the chaperonin is apparently normal (as far as it can be determined with current methodologies) but it actively contributes to pathology, for example in certain types of cancer, and autoimmune and chronic inflammatory disorders. In cer…

HEAT SHOCK PROTEINS AND ULCERATIVE COLITIS: THE START OF A NEW ERA?

2015

We read with great interest the article written by Abou El Azm and coworkers, published in the last issue of the Arab Journal of Gastroenterology [1]. In this article, the authors investigated the molecular expression of heat shock proteins (HSP) 70 and 90 in relation to the grades of inflammation and dysplasia in patients with ulcerative colitis (UC) before and after treatment. In this study, in agreement with other published studies [2–4], the authors not only found a potential role for HSP 70 and HSP 90 for assessment of the activity and prognosis of UC, but also such markers predicted the presence of dysplasia and differentiated it from reactive atypia [1]. HSP had been found not only a…

Chaperons moleculae in brain tumors-CHAMOBRAT TRIAL: HSP60 and microRNAs related levels in tissue and circulating exosomes in human brain tumors befo…

Current regimen for high-grade gliomas is maximal safe surgical resection followed by external beam radiotherapy with concurrent temozolamide. Maximal tumor resection, however, must be balanced with preservation of the patient’s neurological function. A crucial prognostic factor in oncological neurosurgery is the extent of resection. Several studies have addressed the importance of extent of resection in gliomas surgery. Despite development in the fields of pre operative and intraoperative neuroimaging and neuromonitoring have ameliorated the survival rate and the quality of life for patients affected by high grade gliomas, the clinical outcome of patients with such gliomas remains extremel…

A multipronged approach to unveil the emerging role of Hsp60 in chronic obstructive pulmonary disease

2011

Inflammation is a major component of chronic obstructive pulmonary disease (COPD) and its cause and mechanisms are still incompletely understood. For example, the role of heat shock proteins (Hsps), many of which are molecular chaperones, has not been explored in detail in COPD, despite the fact that these molecules are known to participate in inflammation in other diseases. It has been shown that extracellular Hsps can signal certain types of T cells, macrophages, dendritic cells, and neutrophils and, thereby, elicit inflammation and immunity. However, these phenomena have not been investigated in COPD despite: a) the increasing awareness of Hsp participation in inflammation and immunity; …

Heat Shock Proteins in Multiple Sclerosis Pathogenesis: Friend or Foe?

2015

Multiple Sclerosis is a complex chronic inflammatory, neurodegenerative disease conditioned by genetic, epigenetic and environmental factors. Main pathological features of MS include areas of focal demyelination of white matter characterized by gliosis, neuron and oligodendrocyte loss. Neurodegenerative as well as immune-mediated processes play a role in the pathogenesis of this disease. One of these immunogenic factors could be represented by the heat shock proteins. HSP exhibit cytoprotective and cytostimulatory effects due to their molecular chaperones role, in many brain model misfolding diseases such as Alzheimer’s and Parkinson’s diseases, whereas still no unambiguous results have bee…
