'Carica papaya leaves have been used for traditional treatment of dengue fever and have been reported to exhibit an immunomodulatory activity by affecting the level of cytokine production in vitro and in vivo. Due to the lack of adequate in vivo evidence in dengue disease model, the present study was ... More
Loss of MAPK-activated protein kinase 2 enables potent dendritic cell-driven anti-tumour T cell response.

'Maintaining dendritic cells (DC) in a state of dysfunction represents a key mechanism by which tumour cells evade recognition and elimination by the immune system. Limited knowledge about the intracellular mediators of DC dysfunction restricts success of therapies aimed at reactivating a DC-driven anti-tumour immune response. Using a cell type-specific ... More
Dual Inhibition of PI3K/Akt and mTOR by the Dietary Antioxidant, Delphinidin, Ameliorates Psoriatic Features In Vitro and in an Imiquimod-Induced Psoriasis-Like Disease in Mice.

'The treatment of psoriasis remains elusive, underscoring the need for identifying novel disease targets and mechanism-based therapeutic approaches. We recently reported that the PI3K/Akt/mTOR pathway that is frequently deregulated in many malignancies is also clinically relevant for psoriasis. We also provided rationale for developing delphinidin (Del), a dietary antioxidant for ... More
Ventilator-induced lung injury is aggravated by antibiotic mediated microbiota depletion in mice.

'Antibiotic exposure alters the microbiota, which can impact the inflammatory immune responses. Critically ill patients frequently receive antibiotic treatment and are often subjected to mechanical ventilation, which may induce local and systemic inflammatory responses and development of ventilator-induced lung injury (VILI). The aim of this study was to investigate whether ... More
Anti-inflammatory and anti-chemotactic effects of dietary flaxseed oil on CD8(+) T cell/adipocyte-mediated cross-talk.

PubMed ID26616354
CD8(+) T cell/adipocyte paracrine interactions represent a critical step in the development of the obese inflammatory phenotype that is disrupted by long-chain n-3 PUFA. Our objective was to determine the effect of flaxseed-derived n-3 PUFA (a-linolenic acid) on these paracrine interactions. ... More
Gelatinase B/matrix metalloproteinase-9 is a phase-specific effector molecule, independent from Fas, in experimental autoimmune encephalomyelitis.

Gelatinase B/matrix metalloproteinase-9 (MMP-9) triggers multiple sclerosis (MS) and the animal model of experimental autoimmune encephalomyelitis (EAE) by the breakdown of the blood-brain barrier. Interestingly, MMP-9 is beneficial in systemic autoimmunity caused by Fas-deficiency. Fas-deficient (faslpr) and Fas-ligand-deficient mice are protected against EAE. We here investigated the interaction between Fas ... More
Synergistic effect of dual targeting vaccine adjuvant with aminated ß-glucan and CpG-oligodeoxynucleotides for both humoral and cellular immune responses.

Presently, clinically approved adjuvants (such as aluminum salts) fail to induce cellular immune responses, which is crucial to defend against intracellular pathogens (including HIV, malaria, tuberculosis and Ebola) and cancer. However, Freund's complete adjuvant potently stimulates both humoral and cellular immune responses, accompanying by high toxicity and severe side reactions. ... More
Chronic psychosocial stress compromises the immune response and endochondral ossification during bone fracture healing via ß-AR signaling.

Chronic psychosocial stress/trauma represents an increasing burden in our modern society and a risk factor for the development of mental disorders, including posttraumatic stress disorder (PTSD). PTSD, in turn, is highly comorbid with a plethora of inflammatory disorders and has been associated with increased bone fracture risk. Since a balanced ... More

The terminal complement complex (TCC) is formed on activation of the complement system, a crucial arm of innate immunity. TCC formation on cell membranes results in a transmembrane pore leading to cell lysis. In addition, sublytic TCC concentrations can modulate various cellular functions. TCC-induced effects may play a role in ... More
