Many binding actin proteins are expressed in eukaryotic cells. This polypeptide helps stabilize and reset the Cytoskeleton Actin organization in response to external stimuli, or during cell migration and adhesion. Here we review a certain set of binding actin proteins called plastin. Plastins (also called Fimbrins) belonging to the subclass of protein that binds aktin known as actin bundling proteins. Three isoforms have been marked on mammals: T-plastin is expressed in cells from solid tissue, while L-Plastin occurs mainly in hematopoietic cells. Third isoform, i-plastin, specifically expressed in the small intestine, large intestine and kidneys. These proteins share unique properties of actin filaments that connect cross into a tight bundle. Although plastins are mainly involved in Actin Cytoskeleton regulations, they have several unique features. For example, they are involved in invasion by pathogenic bacteria such as Shigella Flexneri and Salmonella typhimurium.
Also, L-Plastin plays an important role in the leukocyte function. T-plastin, on the other hand, might be involved in repairing DNA. Finally, both T-and L-plastin engaged in several diseases, and L-Plastin is considered a valuable marker for cancer. This paper is critical to review the data reported regarding the transmission of the Helicobacter pylori. Transmission mode remains poorly understood; There is no single transmission line that has been clearly identified. Laboratory studies have experienced difficulties in isolating these organisms from materials other than gastric tissue. The problematic detection of these bacteria has presented obstacles to showing incoming and outgoing portals and to involve or override the environmental reservoir. It is shown additional that knowledge of transmission of H. Pylori is limited because of the lack of solid epidemiological evidence of population-based analysis that is enough to consider confounding.
Observations reported generally support the transmission mode of people-to-people most often occur at the beginning of life; H. Pylori is consistently linked to conditions related to housing crowding in childhood. Laboratory studies have produced evidence that supports feces and oral-oral lines.
Human lung cancer cells express receptors such as functionally active tolls 9.
BACKGROUND
CPG-Oligonucleotides (CPG-odn), which induces signaling through receptors such as toll (TLR9), is currently being investigated as an adjuvant in therapy against infection and cancer. The CPG-ODN function as Ajuvan T-1 and is able to activate dendritic cells. The TLR9 man has been described strongly expressed in B-lymphocytes, monocytes, plasmacytoid dendritition cells and at low levels in human respiratory cells. We determine whether the direct interaction of bacterial DNA with tumor cells itself is possible and investigating the expression and function of TLR9 in solid tumors and malignant cell lines. TLR9 expression by malignant tumor cells, will affect the treatment approach using CPG-odn on the one hand, and, on the other hand, providing additional new information about the role of tumor cells in immunological tumors.
Method.
TLR9 expression in non-small lung cancer that is not repaired, non-malignant networks and tumor cell lines are considered to use immunohistochemicals, confocal microscopes, in situ hybridization, RT-PCR and UU-DNA. Apoptosis and memokin expressions are detected by facial analysis and bio-plex systems.
Results
We found the intensity of high TLR9 signals in tumor cell cytoplasm in the majority specimens of lung cancer and in all tumor cell lines tested. Unlike this non-malignant lung tissue only shows a weak expression sporadically. Hella cell stimulation and A549 with CPG-odn induction secretion of Kimoatractan monocyte-1 protein and reducing spontaneous necrosis factors and tumors-alpha induces apoptosis.
Plastins: versatile modulators of actin organization in (patho)physiological cellular processes.
Salmonella: immune response and vaccine.
Salmonella infection is a serious medical and veterinary problem throughout the world and causes fears in the food industry. Vaccination is an effective tool for prevention of salmonella infection. The host’s resistance to Salmonella initially depends on the production of inflammatory cytokines that lead to active infiltration of inflammatory cells on the network. After that specific immunity T-and B-cell-B cells allow the cleansing of salmonella microorganisms from networks and long-lasting immunity formation for re-infection. Increased resistance that develops after primary / vaccination infection requires the cytokine of cells such as IFNGAMA TNFALPHA and IL12 other than opsonising antibodies. But for reasons that are not fully understood seroconversion and / or the existence of cell memory that can be detected does not always correlate with the development of resistance obtained against infection.
Cells that are killed by vaccines and subunit vaccines are used in prevention of salmonella infection in animals and in humans with variable results. A number of initial Salmonella live vaccines originate empirically by chemicals or u.v. Mutagenesis proved immunogenic and protective and still used even though it needed repeated parenteral administration. Progress recently in the genetic knowledge of the virulence of Salmonella and modern recombinant DNA technology offers the possibility to introduce some defined and irreversible mutations into the bacterial genome. This recently allows the development of salmonella strains without significant side effects but still able to induce solid immunity after a single oral administration.

Entisted Salmonella vaccines have been used for antigen / heterologous protein expressions that can be successfully delivered to the immune system. Furthermore, Salmonella can transfer plasmids that encode foreign antigens under the control of eukaryotic promoters (DNA vaccines) on cells that present antigens that result in delivery of DNA vaccines targeted at these cells. Apart from the recent progress in the development of Salmonella vaccine most of the work has been carried out in laboratory mice and more research on other animal species.
