Kinome analysis of Toll-like receptor signaling in bovine monocytes.

The Toll-like receptors (TLRs) are a family of pathogen recognition receptors that alert the host to the presence of microbial challenge. Each TLR responds to a specific microbial associated ligand. For example, TLR4 is activated by lipopolysaccharide (LPS), whereas TLR9 responds to microbial DNA (CpGs).

Genome to kinome: species-specific peptide arrays for kinome analysis.

Tools for conducting high-throughput kinome analysis do not exist for many species. For example, two commonly used techniques for monitoring phosphorylation events are phosphorylation-specific antibodies and peptide arrays. The majority of phosphorylation-specific antibodies are for human or mouse targets, and the construction of peptide arrays relies on information from phosphorylation databases, which are similarly biased toward human and mouse data.

Microarray analysis of Streptococcus pneumoniae gene expression changes to human lung epithelial cells.

Streptococcus pneumoniae infection starts from the respiratory tract where interaction with host epithelial cells occurs. To gain more insights on pneumococcal pathogenesis, an oligonucleotide (oligo)-based microarray was used to investigate gene expression changes of one serotype 3 encapsulated pathogenic S. pneumoniae strain 82 and one unencapsulated avirulent S.

Comparative approaches to the investigation of responses to stress and viral infection in cattle.

Fatal bovine respiratory disease (BRD) is a major cause of financial losses in the cattle industry. A variety of stressors have been implicated as contributing to disease severity. However, it has proven difficult to determine the role these individual factors may play in the final outcome of this disease complex.

Molecular analyses of disease pathogenesis: application of bovine microarrays.

The molecular analysis of disease pathogenesis in cattle has been limited by the lack of availability of tools to analyze both host and pathogen responses. These limitations are disappearing with the advent of methodologies such as microarrays that facilitate rapid characterization of global gene expression at the level of individual cells and tissues. The present review focuses on the use of microarray technologies to investigate the functional pathogenomics of infectious disease in cattle.
