Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

Phage Therapy: Targeting the Gut Microbiota for the Treatment of Acute Pancreatitis

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Acute pancreatitis (AP) is a common clinical inflammatory condition whose severity is closely associated with both local pancreatic injury and systemic complications. Research indicates that gut microbiota dysbiosis and subsequent bacterial translocation can exacerbate disease progression via the gut–pancreas axis, representing a critical ...

Neutralization of IFN-γ reverts clinical and laboratory features in a mouse model of macrophage activation syndrome. [PDF]

, 2018
BACKGROUND: The pathogenesis of macrophage activation syndrome (MAS) is not clearly understood: a large body of evidence supports the involvement of mechanisms similar to those implicated in the setting of primary hemophagocytic lymphohistiocytosis ...

IL‐15 Plus Thymosin α1 Reduces Senescent Hepatic CD8+ T Cells in Hepatocellular Carcinoma via PI3K/AKT Suppression

Journal of Gastroenterology and Hepatology, EarlyView.
Combined IL‐15 and thymosin α1 therapy reverses CD8+ T cell senescence in hepatocellular carcinoma via a “supply and boost” strategy. Tα1 restores thymic naïve T cell output, while IL‐15 enhances peripheral effector function. Mechanistically, this combination suppresses overactivated PI3K/AKT signaling, restoring antitumor immunity and prolonging ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Correlation between TLR9 Expression and Cytokine Secretion in the Clinical Diagnosis of Systemic Lupus Erythematosus

Mediators of Inflammation, 2015
To investigate the correlation between TLR9 and cytokine secretion in SLE diagnosis and treatment. A total of 66 cases (39 SLE and 27 healthy donors) were enrolled in this study. The CD20+ labeled B cells were isolated from SLE patients.

TLR9 Turns the Tide on Treg Cells [PDF]

Immunity, 2008
In this issue of Immunity, Hall et al. (2008) demonstrate that commensal bacterial DNA can suppress Treg cell conversion via TLR9-mediated activation of lamina propria dendritic cells and thus potentially disrupt intestinal homeostasis.

Toll Like Receptor 4: A Potential Link Between Obesity and Metabolic Diseases

Obesity Reviews, EarlyView.
ABSTRACT Epidemiological evidence shows that obesity increases the risk of developing metabolic diseases. Nevertheless, the mechanisms behind this connection remain underappreciated. The substantial impact of these disorders on global health has led to extensive research efforts aimed at identifying the pathophysiological links between them.
