Fight or flight? – Flight increases immune gene expression but does not help to fight an infection

Flight represents a key trait in most insects, being energetically extremely demanding, yet often necessary for foraging and reproduction. Additionally, dispersal via flight is especially important for species living in fragmented landscapes. Even though, based on life-history theory, a negative relationship may be expected between flight and immunity, a number of previous studies have indicate...

Methylation on RNA: A Potential Mechanism Related to Immune Priming within But Not across Generations

Invertebrate immune priming is a growing field in immunology. This phenomenon refers to the ability of invertebrates to generate a more vigorous immune response to a second encounter with a specific pathogen and can occur within and across generations. Although the precise mechanism has not been elucidated, it has been suggested that methylation of DNA is a cornerstone for this phenomenon. Here...

Environmental change mediates mate choice for an extended phenotype, but not for mate quality

Sexual cues, including extended phenotypes, are expected to be reliable indicators of male genetic quality and/or provide information on parental quality. However, the reliability of these cues may be dependent on stability of the environment, with heterogeneity affecting how selection acts on such traits. Here, we test how environmental change mediates mate choice for multiple sexual traits, i...

TLR8, but not TLR7, induces the priming of the NADPH oxidase activation in human neutrophils.

Neutrophils play a key role in host defense against invading pathogens by releasing toxic agents, such as ROS and antimicrobial peptides. Human neutrophils express several TLRs that recognize a variety of microbial motifs. The interaction between TLR and their agonists is believed to help neutrophils to recognize and to kill pathogens efficiently by increasing their activation, a process called...

Developmental plasticity of CNS microglia.

Microglia arise from CD45(+) bone marrow precursors that colonize the fetal brain and play a key role in central nervous system inflammatory conditions. We report that parenchymal microglia are uncommitted myeloid progenitors of immature dendritic cells and macrophages by several criteria, including surface expression of "empty" class II MHC protein and their cysteine protease (cathepsin) profi...
