Report on Gaucher Disease (Medical Sciences)

This deregulation of immune system cells is tightly related to the increased levels of cytokines and chemokines. These molecules are secreted by the immune cells, which, in turn, are recruited and activated by chemokines and cytokines, respectively. This could create a loop in which immune cells from Gaucher patients are being continuously activated, leading to systemic and focal activation of the immune system. The molecular and cellular bases of GD bone physiopathology are not well understood and opposing studies have emerged in the last few years. As mentioned before in , Mistry et al. The most striking feature about this model is the presence of bone involvement as previous mouse models of GD did not present bone involvement.

Bone manifestations included medullar infarctions with associated avascular necrosis and osteopenia at all sites. The bone formation rate presented a significant impairment in these mice while the quantification of TRAP-labeled surfaces did not present differences. A significant impairment in osteoblast proliferation and differentiation was present in the model, while osteoclast differentiation and activity did not seem to be altered. The impairment on osteoblast proliferation was shown to be dependent on a decrease in PKC activity due to the accumulation of glucosylsphingosine and, to a lesser extent, glucosylceramide.

More recent studies present sphingosine as the most probable candidate for osteoblast impairment in the mouse model [ 54 ]. These findings suggest that bone complications in GD would result from an osteoblast source without osteoclast involvement [ 50 , 54 ]. Different reports have shown the involvement of osteoclasts on GD bone pathophysiology. Our group showed, using a similar approach, that treatment of osteoclast precursors with conditioned media from peripheral blood mononuclear cells PBMCs exposed to CBE resulted in an increased level of osteoclast differentiation when compared to control conditioned media.

In addition to this we could show that treatment of the osteoblastic cell line MC3T3 with conditioned media from CBE treated M reduced mineralization and collagen deposit [ 57 ]. These results would indicate an impairment of both osteoclast and osteoblast activity in GD leading to bone loss as the involvement of immune cells and molecules in this process. The group of Reed et al. GD is the most common lysosomal disorder and the first for which specific treatment has been developed. Bone disease in Gaucher patients is one of the most disabling features of the disease, so the possibility of knowing the mechanisms underlying the bone pathology is a main challenge to ameliorate the quality of life of patients.

Studies are based on the explanation of the cellular and molecular pathways that result upon glucosylceramide accumulation in M and the possible relationship with different bone cells. The bases of osteoimmunology are being applied to bring light in this aspect. In this regard, there are several questions to be answered. On the other hand, crosstalk between osteoblasts and osteoclasts in GD could provide new mechanisms involved in the process of bone loss.

Finally the effect of ERT and substrate reduction therapy on bone involvement is a central aspect to be studied, especially, how these treatments affect different bone cells and their function. The results of basic research will be of utility in order to identify new targets for coadjuvant therapies to treat skeletal pathology in GD.

Received 08 Oct Revised 09 Jan Accepted 11 Jan Published 03 May Abstract Gaucher, the most prevalent lysosomal disorder, is an autosomal recessive inherited disorder due to a deficiency of glucocerebrosidase. Osteoimmunology A diverse number of interactions between bone and immune cells occur within the bone microenvironment. Osteoimmunology in Pathological Conditions The activation of immune cells is a requisite for defense of the host against pathogens; however, a persistent overactivation of effector cells under certain pathological conditions can result in tissue damage. Inflammation in Gaucher Disease A chronic stimulation of the immune system is a well-accepted hallmark in GD. Osteoclast-Osteoblast Uncoupling in Gaucher Disease The molecular and cellular bases of GD bone physiopathology are not well understood and opposing studies have emerged in the last few years.

Future Perspectives GD is the most common lysosomal disorder and the first for which specific treatment has been developed.

Weinreb, P. Type 2 causes very serious brain abnormalities and is usually fatal before the age of two, while Type 3 affects children and adolescents. The condition is a recessive genetic disorder, meaning that both parents must be carriers for a child to suffer from Gaucher.

However, said Dr. Feldman, studies have found that people with only one copy of a mutated Gaucher gene—those known as carriers—are at an increased risk of developing Parkinson's disease. Albert Reece, M. Feldman and his colleagues used the new reprogramming technology developed by Shinja Yamanaka in Japan, who was recognized with this year's Nobel Prize for Medicine or Physiology. Scientists engineered cells taken from the skin of Gaucher patients, creating human induced pluripotent stem cells, known as hiPSC—stem cells that are theoretically capable of forming any type of cell in the body. Scientists differentiated the cells to form white blood cells known as macrophages and neuronal cells. A key function of macrophages in the body is to ingest and eliminate damaged or aged red blood cells.

In Gaucher disease, the macrophages are unable to do so—they can't digest a lipid present in the red blood cell membrane. The macrophages become engorged with lipid and cannot completely clear the ingested red blood cells. This results in blockage of membrane transport pathways in the macrophages lodged in the bone marrow, spleen and liver. The macrophages that the scientists created from the reprogrammed stem cells exhibited this characteristic hallmark of the macrophages taken from Gaucher patients. To further test the stem cells, the scientists administered a recombinant enzyme that is effective in treating Gaucher patients with Type 1 disease. When the cells were treated with the enzyme, the function of the macrophages was restored—they completely cleared the red blood cells.

Feldman is already using these Gaucher patient-derived macrophages to better understand the disease fundamentals and to find novel medicines for Gaucher disease treatment. Clinical applications include not only transplantation of stem cells, but also the use of stem cells for drug discovery as Dr. Feldman's studies so beautifully illustrate. Explore further.
