Citoesqueleto by Paulo Trivellato on Prezi

In the prior art there are described compounds agonists activity of HDAC proteins, which can be used within micrrotubulos scope of this invention as agonists HADC6 protein, and below by way of illustration without this implying a limitation to the scope of the present invention: Activation of T cells requires antigen binding properly presented by molecules of the major histocompatibility complex antigen presenting cells. Cytoskeletal polarization of T cells is regulated by an immunoreceptor tyrosine-based activation motif-dependent odganizador.

Structural insights into microtubule function. For immunoblot experiments, 4. In contrast, CD69 expression was stimulated equally in all cells studied unaffected by any treatment Fig. Method of identifying and evaluating the activity regulating compounds HDAC6 protein on the activation of T lymphocytes characterized in that it comprises the following steps: Then the cells were stained for LFA-1 and analyzed by confocal microscopy.

However, there are increasing evidence that other cytoskeletal proteins involved in this process, but to date has not linked the microtubule acetylation with immune pathology.

T cell effector functions: Kind code of ref document: This enzyme deacetylated tubulin in cells and its activity it can be inhibited by trichostatin A and tubacin pharmacological agents Hubbert, C. Raji cells were labeled with orvanizador probe CMAC.

The results of the present invention demonstrate that microtubules also play a cetnro in early and late activation of T cell receptor antigen binding T cell modifies microtubule acetylation in a dynamic way initially They are deacetylated, for about 15 minutes after gradually reacetilen.

However, the staining was weak in both untreated cells and cells treated with butyrate or trapoxinaB Fig.

Dynamic polarization of the microtubule cytoskeleton during CTL-mediated killing. Date of ref document: Nature; Matsuyama, A.

Moreover, activators or agonists HDAC6 compounds could play a role in reducing damage associated with an exacerbated immune responses such as those taking place in an autoimmune disease.

From this moment, tubulin acetylation increased progressively reaching a peak after two hours of stimulation Fig. These data clearly showed that could distinguish two phases during tubulin acetylation mediated superantigen. Together these results demonstrate that HDAC6 polarizes toward the contact area with antigen presenting cell where the enzyme activity occurs. Furthermore, the origin of these compounds candidates for the identification method of the invention can be varied so that can be natural e.

Country of ref document: Nature; Grakoui, A. Furthermore, microtubules acetylated T cells were surrounding the central and peripheral typical markers of immune synapses are CD3 and adhesion molecule LFA-1, respectively Fig.

HDAC6 is a microtubule-associated deacetylase. Tyrosine-phosphorylated T cell receptor zeta chain associates with the actin cytoskeleton upon activation of mature T lymphocytes.

Nature82 ; Grakoui, A. Trapoxina B fue generosamente cedida por el Dr.

The molecular weight markers are indicated on the left. Cell Biol 95, ; J77 and Raji cells were contacted in the presence of SEE or SEB for the indicated times, and then the levels of acetylated tubulin and tubulin by microhubulos under nonreducing conditions were detected. Sawing, JM, Nieto, M. Potent inhibitors Histone deacetylase built from trichostatin A and cyclic tetrapeptide antibiotics Including trapoxin.


Viable cells after 24 hours after being transfect das were isolated by centrifugation on a Ficoll gradient and placed in contact micrptubulos Raji cells to conduct functional studies.

Every 30 seconds series of images of fluorescence and differential interference contrast of J77 cells transfected with HDAC6 microtubulps obtained from the beginning and contacting with Raji cells pulsed with SEE. Therefore, regulation of the immune response is crucial in the treatment of the most important causes of morbidity and mortality in our society.

The membrane-microfilament linker ezrin is Involved in the formation of the immunological synapse and in T cell activation. Three-dimensional supramolecular activation clusters of seggregation in T cells. The following describes in detail the materials and methods used to perform the examples of the present invention.

Isoflurane, a commonly used volatile anesthetic, enhances renal cancer microhubulos and malignant potential via the hypoxia-inducible factor cellular signaling pathway in vitro.

Therefore, it is ascribed to the pharmacological and biomedical sector for application in the health jicrotubulos.
