REVIEW
Natalia Muñoz-Wolf, Ed C Lavelle
Growing awareness of the multiplicity of roles for the IL-1 family in immune regulation has prompted research exploring these cytokines in the context of vaccine-induced immunity. While tightly regulated, cytokines of the IL-1 family are normally released in response to cellular stress and in combination with other danger/damage associated molecular patterns (DAMPs), triggering potent local and systemic immune responses. In the context of infection or autoimmunity, engagement of IL-1 family receptors links robust innate responses to adaptive immunity...

The NLR pyrin domain-containing protein 3 (NLRP3) inflammasome, a multi-protein complex, produces the pro-inflammatory cytokines interleukin (IL)-1β and IL-18, which may contribute to the development of airway inflammation in chronic obstructive pulmonary disease (COPD). The aim of this study was to explore the correlation between circulating and local airway NLRP3 inflammasome activation with acute exacerbation of COPD (AECOPD). mRNA levels of NLRP3, Caspase (Casp)-1, apoptosis-associated speck-like protein containing CARD (ASC), IL-18, and IL-1β in peripheral blood mononuclear cells (PBMCs) and bronchial tissues were determined by real-time PCR in 32 smokers, 65 patients with AECOPD, 50 COPD patients in recovery stage, and 30 COPD patients in stable stage...

Although inflammation is a biological phenomenon that exists to protect the host against infections and/or related problems, its unceasing activation results in the aggravation of several medical conditions. Imidazoles, whether natural or synthetic, are molecules related to a broad spectrum of biological effects, including anti-inflammatory properties. In this study, we screened eight novel small molecules of the imidazole class synthesized by our research group for their in vitro anti-inflammatory activity...

Acute lung injury (ALI), known a severe disease along with high morbidity and mortality, is lacking of specific therapies. Inflammation, apoptosis and oxidative stress are critical pathologies that contribute to ALI. Recently, there is study indicated that NLRP9b, a NOD-like receptor (NLR) member, is critical in modulation of inflammatory response. However, the effects of NLRP9b on sepsis-associated ALI, and the underlying molecular mechanism have not been understood. In the present study, the wild type (WT) and NLRP9b-knockout (NLRP9b-/- ) mice with C57B/L6 background were subjected to a cecal ligation and puncture (CLP) for ALI murine model establishment...

Resistin, a previously discovered cysteine-rich adipokine known to regulate glucose metabolism, has been emerged as a mediator in inflammation and immunity. Its level was supposed to be related to the expression of indicators, such as interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) in inflammation. Toll-like receptor 4 (TLR4) was reported to be a receptor for resistin in cells, like leukocytes and peripheral blood mononuclear cells (PBMC). However, the pro-inflammatory role of resistin and its intracellular mechanisms in alveolar macrophages have not been thoroughly validated...

Orthodontic tooth movement relies on coordinated tissue resorption and formation in the surrounding bone and periodontal ligament. Tooth loading causes local hypoxia and fluid flow, initiating an aseptic inflammatory cascade culminating in osteoclast resorption in areas of compression and osteoblast deposition in areas of tension. Compression and tension are associated with particular signaling factors, establishing local gradients to regulate remodeling of the bone and periodontal ligament for tooth displacement...

BACKGROUND: In the early phases of relapsing-remitting multiple sclerosis (RR-MS), a clear correlation between brain lesion load and clinical disability is often lacking, originating the so-called clinico-radiological paradox. Different factors may contribute to such discrepancy. In particular, synaptic plasticity may reduce the clinical expression of brain damage producing enduring enhancement of synaptic strength largely dependent on neurotrophin-induced protein synthesis. Cytokines released by the immune cells during acute inflammation can alter synaptic transmission and plasticity possibly influencing the clinical course of MS...
