Streptococcus suis 2 is an important swine pathogen and an emergent zoonotic pathogen. Excessive inflammation caused by S. suis is responsible for the high levels of early mortality observed in septic shock-like syndrome cases. However, the mechanisms through which S. suis 2 (SS2) causes excessive inflammation remain unclear. Thus, this study aimed to identify novel pro-inflammatory mediators t...

Extracellular vesicles (EVs) can modulate the host immune response, executing both pro- and anti-inflammatory effects. As EVs increasingly gain attention as potential carriers for targeted gene and drug delivery, knowledge on the effects of EVs on the host immune response is important. This review will focus on the ability of EVs to trigger a pro-inflammatory host response by activating target ...

multiple sclerosis (ms) is an autoimmune disease characterized by recurrent episodes of demyelination and axonal lesion mediated by cd4+ t cells with a proinflammatory t helper (th)1 and th17 phenotypes, macrophages, and soluble inflammatory mediators. the overactive  pro-inflammatory  th1  cells  and  clonal  expansion  of  b  cells  initiate  an inflammatory cascade with several cellular and ...

Switching microglia from a disease exacerbating, ‘pro-inflammatory’ state into neuroprotective, ‘anti-inflammatory’ phenotype is promising strategy for addressing multiple neurodegenerative diseases.

background: multiple sclerosis (ms) is a demyelinating disease of the central nervous system and cytokines may play a role in the development of ms lesions. objective: to determine levels of different cytokines in patients with relapsing-remitting ms (rr-ms) compared to healthy controls. methods: profiles of pro-inflammatory, th1-, th2-, and th17-related cytokines were compared by quantitative ...

Microglial activation results in profound morphological, functional and gene expression changes that affect the pro- and anti-inflammatory mechanisms of these cells. Although statins have beneficial effects on inflammation, they have not been thoroughly investigated for their ability to affect microglial functions. Therefore the effects of rosuvastatin, one of the most commonly prescribed drugs...

BACKGROUND Innate immunity is the first line of defence offered by host cells to infections. Macrophage cells involved in innate immunity are stimulated by lipopolysaccharide (LPS), found on bacterial cell surface, to express a complex array of gene products. Persistent LPS stimulation makes a macrophage tolerant to LPS with down regulation of inflammatory genes ("pro-inflammatory") while conti...

depression is a mental disorder that results from changes in the central nervous system (cns) that may result from immunological abnormalities. according to the world health organization, major depression will become the leading cause of disability worldwide. accumulating evidence has indicated the existence of reciprocal communication pathways between nervous, endocrine and immune systems. the...

The recently described IL-33 acts as a pro-inflammatory cytokine, inducing the expression of multiple responses in the target cells. Although a nuclear localization of IL-33 has been described, its exact functional relevance is presently unknown. The present study was conducted to analyze the effects of IL-33 on the TNF-α induced synthesis of the ...
