Linking human physiology to inflammatory mechanisms discovered in vitro or in animal models is essential to determine their importance. Innate immunity underlies many of these inflammatory responses in health and disease. Bacterial endotoxin is the quintessential trigger of innate immune responses. When administered to humans, endotoxin has been an important ...

Evidence from rodents established an important role of brown adipose tissue (BAT) in energy expenditure. Moreover, to sustain thermogenesis, BAT has been shown to be a powerful sink for draining and oxidation of glucose and triglycerides from blood. The potential of BAT activity in protection against obesity and metabolic syndrome ...

Hypertrophic scarring leads to a deformed appearance and contracted neogenetic tissue, resulting in physiological and psychological problems for patients. Millions of people suffer these discomforts each year. Emerging evidence has reported that miRNA contributed to hypertrophic scarring or keloid formation. In this study, nine hypertrophic scar samples and the matched ...

Endotoxin tolerance (ET) is a state of reduced responsiveness to endotoxin stimulation after a primary bacterial insult. This phenomenon has been described in several pathologies, including sepsis, in which an endotoxin challenge results in reduced cytokine production. In this study, we show that the NFκ L chain enhancer of activated ...

Resistance to apoptosis is an important characteristic that human macrophages acquire during differentiation from monocytes. However, the intracellular mechanisms that mediate the development of resistance are not well understood. We have used M-CSF-stimulated primary human monocytes and PMA-treated THP1 cells to study apoptosis resistance during differentiation of human macrophages. Our ...

Endogenous retroviruses are the remnants of past retroviral infections that are scattered within mammalian genomes. In humans, most of these elements are old degenerate sequences that have lost their coding properties. The HERV-K(HML2) family is an exception: it recently amplified in the human genome and corresponds to the most active ...

Wnt5a is a secreted pleiotropic glycoprotein produced in an inflammatory state by a wide spectrum of ubiquitous cell populations. Recently, we demonstrated that Wnt5a skews the differentiation of human monocyte derived dendritic cells (moDCs) to a tolerogenic functional state. In this study we focus our interest on the role of ...

Although Leishmania (Viannia) braziliensis is the most prevalent species that cause American tegumentary leishmaniasis (ATL), the immune response against this parasite has been poorly investigated. Upon activation, macrophages produce a series of pro-inflammatory molecules, including the lipid mediator leukotriene B4 (LTB4). LTB4 has been shown to enhance several macrophage functions, ...

Dendritic cells (DCs), monocytes, and macrophages are leukocytes with critical roles in immunity and tolerance. The DC network is evolutionarily conserved; the homologs of human tissue CD141(hi)XCR1(+)CLEC9A(+) DCs and CD1c(+) DCs are murine CD103(+) DCs and CD64(-)CD11b(+) DCs. In addition, human tissues also contain CD14(+) cells, currently designated as DCs, ...

Rationale: Inflammation drives atherogenesis. Animal and human studies have implicated interleukin (IL)-1β in this disease. Moderate hypoxia, a condition that prevails in the atherosclerotic plaque, may conspire with inflammation and contribute to the evolution and complications of atherosclerosis through mechanisms that remain incompletely understood. Objective: This study investigated the links ...

Chemokines play essential roles during inflammatory responses and in pathogenesis of inflammatory diseases. Monocyte chemotactic protein-1 (MCP-1) is a critical chemokine in the development of atherosclerosis and acute cardiovascular syndromes. MCP-1, by its chemotactic activity, causes diapedesis of monocytes from the lumen to the subendothelial space that leads to atherosclerotic ...

Accumulating evidence suggests that microRNA-590 (miR-590) has protective effects on cardiovascular diseases, but the mechanism is unknown. Interestingly, previous studies from our laboratory and others have shown that macrophage-derived lipoprotein lipase (LPL) might accelerate atherosclerosis by promoting lipid accumulation and inflammatory response. However, the regulation of LPL at the post-transcriptional ...

The outcome following injury can be healing, repair or regeneration, all of which initiate within a resolving inflammatory response. Regeneration, comprising the complete anatomical and functional restoration of lost tissue with minimal residual consequence of injury, is the outcome that most holistically restores prior function. Leukocytes are recognized as playing ...

Crucial to the defense against Leishmania is the ability of the host to mount a cell-mediated immune response capable of controlling and/or eliminating the parasite. The composition of the cell populations recruited in the early phase of the infection seems to be essential for defining the infection outcomes. The signals ...

Efficient local monocyte/macrophage recruitment is critical for tissue repair. Recruited macrophages are polarised towards classical (pro-inflammatory) or alternative (pro-healing) activation in response to cytokines, with tight temporal regulation crucial for efficient wound repair. Estrogen acts as a potently anti-inflammatory regulator of cutaneous healing. However, understanding of estrogen/estrogen receptor contribution to ...

Significance: Postnatal wounds heal with characteristic scar formation. In contrast, the mid-gestational fetus is capable of regenerative healing, which results in wound repair that is indistinguishable from uninjured skin. However, the underlying mechanisms of fetal regenerative phenotype are unknown. Recent Advances: The potent anti-inflammatory cytokine, interleukin-10 (IL-10), plays an essential ...

Murine models of Leishmania major infection in the 1980's revealed two distinct, counter-regulatory populations of CD4(+) T helper (Th) cells, delineated Th1 and Th2, and their archetypal cytokines, interferon gamma (IFN-γ) and interleukin (IL)-4/IL-13, which promoted resistance/susceptibility to infection, respectively. However, the introduction of global cytokine-deficient mice in the 1990's ...

We consider that from the wound to the healing process, the physiology point key to linkage of the process is still unclear. The process from inflammation to the wound healing is divided into three phases: (1) inflammation process, (2) tissue formation, and (3) tissue remodeling. The inflammation program includes cell ...

The intestinal epithelium constitutes a dynamic physical barrier segregating the luminal content from the underlying mucosal tissue. Following injury, the epithelial integrity is restored by rapid migration of intestinal epithelial cells (IECs) across the denuded area in a process known as wound healing. Hence, through a sequence of events involving ...

Macrophages are essential for the efficient healing of numerous tissues, and they contribute to impaired healing and fibrosis. Tissue repair proceeds through overlapping phases of inflammation, proliferation, and remodeling, and macrophages are present throughout this progression. Macrophages exhibit transitions in phenotype and function as tissue repair progresses, although the precise ...

Immune function early in life can be influenced by parental effects and the environment, but it remains unclear how these two factors may interact to influence immunocompetence. We evaluated maternal and environmental contributions to offspring healing ability in a viviparous reptile, the northern watersnake (Nerodia sipedon). We measured wound healing ...

Meniscal tears are relatively common injuries sustained by athletes and non-athletes alike and have far reaching functional and financial implications. Studies have clearly demonstrated the important biomechanical role played by the meniscus. Long-term follow-up studies of post-menisectomy patients show a predisposition toward the development of degenerative arthritic changes. As such, ...

Fibrosis is an intrinsic response to chronic injury, maintaining organ integrity when extensive necrosis or apoptosis occurs. With protracted damage, fibrosis can progress toward excessive scarring and organ failure, as in liver cirrhosis. To date, antifibrotic treatment of fibrosis represents an unconquered area for drug development, with enormous potential but ...

Chronic nonhealing wounds in the elderly population are associated with a prolonged and excessive inflammatory response, which is widely hypothesized to impede healing. Previous studies have linked alterations in local L-arginine metabolism, principally mediated by the enzymes arginase (Arg) and inducible nitric oxide synthase (iNOS), to pathological wound healing. Over ...
