Molecular biology and pathogenicity of mycoplasmas

Article Abstract:

The cell biology and pathogenic capability of mycoplasmas are investigated. These parasitic bacteria are observed in both plants and animals and manifest a strict host-tissue specificity. The main habitats of mycoplasmas are mucous surfaces or membranes of respiratory and urogenital organs of humans and animals. They lack cell walls and are bounded only by plastic cell membranes. Mycoplasmas act on the immune system by suppression of lymphocytes, stimulate cytokines and increase the cytotoxicity of defense cells such as macrophages, T cells and natural killer cells.

Function and regulation of yeast hexose transporters

Article Abstract:

A study has been conducted to examine the regulation of expression and function of several hexose transporter genes of the baker's yeast Saccharomyces cerevisiae, which has been proven useful for studying the mechanisms of glucose sensing, signaling, and utilization in a eukaryotic cell. Apparently, multiple pathways have been found to regulate the transcription of several members of the HXT gene family in response to different levels of extracellular glucose.

Type III protein secretion systems in bacterial pathogens of animals and plants

Article Abstract:

A study was conducted on type III protein secretion systems to determine its structure, function, regulation and impact on bacterial animal and plant pathogens. Results confirm the important role of type III secretion in injecting proteins into the cytosol of eukaryotic cells. This indicates that type III secretion can be a useful tool for the targeted delivery of engineered proteins to control cellular signal transduction and other processes.
