Brian Salmons, Walter H Gunzburg
The size and speed of release of proteins of different sizes from standard cellulose sulphate capsules (Cell-in-a-Box®) was investigated. Proteins with molecular weights of up to around 70kD can be released. The conformation, charge and concentration of the protein being released play a role in the release kinetics. Small proteins such as cytokines can be easily released. The ability to produce cytokines at a sustained and predefined level from encapsulated cells genetically engineered to overexpress such cytokines and implanted into patients may aid immunotherapies of cancer as well as infectious and other diseases...

Immunoglobulin (IgG) 4-related diseases (IgG4-RDs) are fibro-inflammatory conditions characterized by tumorous swelling and serum IgG4 levels. Intrapelvic IgG4-RD has been subclassified according to the localization site and aortic shape as IgG4-related aortic aneurysms (IgG4-AAs), periaortitis (IgG4-PA), and retroperitoneal fibrosis (IgG4-RF). The IgG4-AA pathogenesis would involve interleukin (IL)-6 upregulation, and Th2-predominant and Treg-activated immune conditions. We characterized the features of intrapelvic IgG4-RD lesions, including presence of vascular lesions...

Interleukin (IL)-4 and IL-13 are related cytokines that regulate many aspects of allergic inflammation. They play important roles in regulating the responses of lymphocytes, myeloid cells, and non-hematopoietic cells. In T-cells, IL-4 induces the differentiation of naïve CD4 T cells into Th2 cells, in B cells, IL-4 drives the immunoglobulin (Ig) class switch to IgG1 and IgE, and in macrophages, IL-4 and IL-13 induce alternative macrophage activation. This review gives a short insight into the functional formation of these cytokine receptors...

Inflammation and B-cell hyperactivation have been associated with non-Hodgkin lymphoma development. This prospective analysis aimed to further elucidate pre-diagnosis plasma immune marker profiles associated with non-Hodgkin lymphoma risk. We identified 598 incident lymphoma cases and 601 matched controls in Nurses' Health Study and Health Professionals Follow-up Study participants with archived pre-diagnosis plasma samples and measured 13 immune marker levels with multiplexed immunoassays. Using multivariable logistic regression we calculated odds ratios and 95% confidence intervals per standard deviation unit increase in biomarker concentration for risk of non-Hodgkin lymphoma and major histologic subtype, stratifying additional models by years (<5, 5 to <10, ≥10) after blood draw...

Idiopathic chronic diarrhea (ICD) is a common ailment affecting captive rhesus macaques ( Macaca mulatta). ICD cases are characterized by diarrhea in the absence of commonly identified diarrheal pathogens and multiple recurrences even after supportive therapy. Histologically, the disease is characterized by lymphoplasmacytic colitis. We identified 35 rhesus macaques euthanized for ICD during a 7-month period and described demographic, clinical, histologic, and immunologic commonalities. We found a trend of historic Campylobacter spp...

AIMS: Tildrakizumab, an interleukin (IL)-23 inhibitor, is indicated for the treatment of moderate to severe chronic plaque psoriasis. Although tildrakizumab is not metabolized by, and does not alter, cytochrome P450 (CYP) expression in vitro, clinically-significant pharmacokinetic effects through changes in systemic inflammation, which alters CYP metabolism, have been well documented. At the time of study conduct, the effect of modulation of inflammation/cytokines, including IL-23 inhibition with tildrakizumab, on CYP metabolism, and therefore the potential for disease-drug interactions, in psoriasis patients was unknown...

We examined the effect of acute and chronic sprint interval training (SIT), with or without prior caffeine intake, on levels of exercise-induced inflammatory plasma cytokines [interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α]. Twenty physically-active men ingested either a placebo ( n = 10) or caffeine ( n = 10) 1 h before each SIT session(13-s × 30-s sprint/15 s of rest) during six training sessions (2 weeks). The early (before, immediately after, and 45 min after the exercise) and late (24 and 48 h after the exercise) cytokine and creatine kinase (CK) responses were analyzed for the first and last training sessions...

Macrophages are highly plastic cells that can either mediate or suppress inflammation, depending on their cellular phenotype and cytokine secretion. Inducing macrophages from an inflammatory ('M1') to anti-inflammatory ('M2') phenotype has significant implications for the treatment of inflammatory diseases and regeneration of injured tissues. Although certain cytokines, such as interleukin-4 and -13, are known to induce this phenotypic switch, their therapeutic use in vivo has both safety and efficacy concerns...

Excessive production of pro-inflammatory cytokines such as interleukin-1β (IL-1β) plays a key role in the pathophysiological development of osteoarthritis (OA). Orexin A is an important peptide of hypothalamic origin, which has displayed its multiple biological functions in several chronic diseases via activation of its specific G-protein coupled receptors, orexin-1 receptor (OX1R) and orexin-2 receptor (OX2R). In this study, we aimed to characterize the protective effects of orexin A against IL-1β-induced degradation of articular cartilage matrixes in human chondrocytes...

Atopic dermatitis (AD) is a chronic inflammatory skin disease. Bleomycin (BLM) contributes to the induction of pulmonary inflammation and fibrosis in animals. Although skin and lung tissue inflammation is closely related in the pathogenesis of allergic diseases, a proper animal model for investigating the relationship between skin and lung inflammation is lacking. Therefore, we developed a mouse model of AD with relapsing dermatitis and pulmonary fibrosis caused by the administration of allergen and BLM. The present study determined whether lung injury caused by the bronchial application of BLM would exacerbate AD-like allergic inflammation induced by 2, 4-dinitrochlorobenzene (DNCB) in NC/Nga mice...
