Depression is an important post-stroke sequela with negative impact on mortality, functional outcome and quality of life. Changes in cytokines have been hypothesized to be associated with the etiology of post-stroke depression (PSD). The altere dhypothalamic-pituitary-adrenal (HPA) functioning is associated with the onset of depression. The activity of HPA could induce the fluctuations of cortisol levels. In this study, we prospectively checked interleukin 6 (IL-6) and cortisol levels in patients with early ischemic stroke...

Toll-like receptor 21 (TLR21) is a non-mammalian TLR that functions similar to mammalian TLR9 in recognizing CpG DNA. In the present study, we identified a TLR21 homologue, LycTLR21, from large yellow croaker (Larimichthys crocea). The complete coding sequence of LycTLR21 is 2946 nucleotides long, encoding a protein of 981 amino acids. The deduced LycTLR21 protein has typical TLR domain architecture, including a signal peptide, 13 leucine-rich repeats (LRRs) in the extracellular region, a transmembrane region, and a cytoplasmic Toll-Interleukin-1 receptor (TIR) domain...

P2X purinoceptor 7 (P2X7) receptor (P2X7R) is known to play a significant role in inflammation and pain-causing diseases, including osteoarthritis (OA). However, the mechanisms of action of P2X7R and its role in OA remain unclear. The articular cartilage is the crucial region in which pathological changes occur in OA, involving the dysregulation of degradation and maintenance mechanisms. In this study, we aimed to reveal the molecular mechanisms of action of P2X7R in articular cartilage in OA-induced pain and inflammation by using AZD9056, an antagonist of P2X7R...

In the pathophysiology of asthma, structural cell dysfunction and concomitant microenvironment changes in airways are crucial to pathological progression, which involves oxidative stress. Caffeic acid phenethyl ester (CAPE) is an active anti-oxidative component obtained from propolis, and has been shown to have beneficial effects on several respiratory disorders, such as chronic obstructive pulmonary disease and lung cancer. However, the impact of CAPE on asthma is not well understood. Therefore, this study investigated the advantages of using CAPE to treat asthma and demonstrated the roles of CAPE in the regulation of airway microenvironments...

IgG4-related disease (IgG4-RD) is a systemic disease characterized by elevated serum IgG4 levels and a strong infiltration of IgG4-positive plasma cells in various organs. IgG4-RD patients also frequently suffer from allergic diseases, including asthma and atopic dermatitis. It is well known that T helper type 2 (Th2) cells have an important role in the initiation of allergic diseases, and Th2 cytokines such as interleukin (IL)-4 and IL-13 promote class switching to IgG4. Therefore, IgG4-RD is considered to be a Th2-predominant disease...

Inflammation induced by traumatic brain injury (TBI) is a complex mediator of morbidity and mortality. We have previously demonstrated the utility of both data-driven and mechanistic models in settings of traumatic injury. We hypothesized that differential dynamic inflammation programs characterize TBI survivors vs. non-survivors, and sought to leverage computational modeling to derive novel insights into this life/death bifurcation. Thirteen inflammatory cytokines and chemokines were determined using Luminex™ in serial cerebrospinal fluid (CSF) samples from 31 TBI patients over 5 days...
