Cytokine-Targeted Therapeutics For Kshv-Associated Disease, Nedaa Alomari, Jennifer Totonchy
Cytokine-Targeted Therapeutics For Kshv-Associated Disease, Nedaa Alomari, Jennifer Totonchy
Pharmacy Faculty Articles and Research
Kaposi’s sarcoma-associated herpesvirus (KSHV) also known as human herpesvirus 8 (HHV-8), is linked to several human malignancies including Kaposi sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman’s disease (MCD) and recently KSHV inflammatory cytokine syndrome (KICS). As with other diseases that have a significant inflammatory component, current therapy for KSHV-associated disease is associated with significant off-target effects. However, recent advances in our understanding of the pathogenesis of KSHV have produced new insight into the use of cytokines as potential therapeutic targets. Better understanding of the role of cytokines during KSHV infection and tumorigenesis may lead to new preventive or therapeutic …

Background: Rheumatoid arthritis (RA) is a chronic multi-system autoimmune disease characterized by inflammatory synovitis. Autoantibodies such as rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) have been implicated in the pathogenesis of RA, and are currently important criteria for diagnosis within the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria.1 Yet, many patients diagnosed with RA do not have measurable circulating ACPA or RF which may result in delayed diagnosis and treatment. After IgG1, IgG4 is the second most predominant isotype among ACPA and RF; however it is not detected in currently available diagnostic assays. Recent …

Prokaryotic aminoacylated‐transfer RNAs often need to be efficiently segregated between translation and other cellular biosynthetic pathways. Many clinically relevant bacteria, including Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus faecalis and Pseudomonas aeruginosa direct some aminoacylated‐tRNA species into peptidoglycan biosynthesis and/or membrane phospholipid modification. Subsequent indirect peptidoglycan cross‐linkage or change in membrane permeability is often a prerequisite for high‐level antibiotic resistance. In Streptomycetes, aminoacylated‐tRNA species are used for antibiotic synthesis as well as antibiotic resistance. The direction of coding aminoacylated‐tRNA molecules away from translation and into antibiotic resistance and synthesis pathways are discussed in this review.

Post-translational modification of bacterial elongation factor P (EF-P) with (R)-β-lysine at a conserved lysine residue activates the protein in vivo and increases puromycin reactivity of the ribosome in vitro. The additional hydroxylation of EF-P at the same lysine residue by the YfcM protein has also recently been described. The roles of modified and unmodified EF-P during different steps in translation, and how this correlates to its physiological role in the cell, have recently been linked to the synthesis of polyproline stretches in proteins. Polysome analysis indicated that EF-P functions in translation elongation, rather than initiation as proposed previously. This was …
