Abstract
The purpose of this study was to investigate how a viral infection affecting the epithelial cells could be influenced by the presence of the opportunistic Staphylococcus aureus soluble mediators. The viral antigens presence, apoptosis and cytokine profiles of HeLa cells infected with HSV-1 and pre-/postreated with different bacterial soluble fractions were evaluated. Soluble bacterial molecules could modulate HeLa cells functions to prevent the development of viral infection, but later stages of viral infection are less affected by bacterial soluble mediators. The in vitro cooperative action of HSV-1 and of S. aureus soluble fractions modulated the immune response of the infected HeLa cells, mainly by triggering the release of pro-inflammatory cytokines.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
Chemistry and Biology of Carbohydrates
Carbohydrates are one of the most abundant natural products and are considered to be extremely important biomolecules for their ever-increasing impact on chemistry and biology. Their role in several important biological processes, notably energy storage, transport, modulation of protein function, intercellular adhesion, malignant transformation, signal transduction, viral, and bacterial cell ...read more
