The CXCL8/IL-8 chemokine family and its receptors in inflammatory diseases

Abstract: Chemokines are small proteins that control several tissue functions, including cell recruitment and activation under homeostatic and inflammatory conditions. CXCL8 (interleukin-8) is a member of the chemokine family that acts on CXCR1 and CXCR2 receptors. CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, and CXCL7 are also ELR+ chemokine members that bind to these receptors, especially CXCR2. The majority of studies on the biology of CXCL8 and their receptors have been performed in polymorphonuclear leukocytes. However, many other cells express CXCR1/CXCR2, including epithelial, endothelial, fibroblasts and neurons, contributing to the biological effects of CXCL8. There is substantial amount of experimental data suggesting that CXCL8 and receptors contribute to elimination of pathogens, but may also contribute significantly to disease-associated processes, including tissue injury, fibrosis, angiogenesis and tumorigenesis. Here, we discuss the biology of CXCL8 family and the potential therapeutic use of antagonists or blockers of these molecules in the context of organ-specific diseases.

Immune responses in neonates

Abstract: Neonates have little immunological memory and a developing immune system, which increases their vulnerability to infectious agents. Recent advances in the understanding of neonatal immunity indicate that both innate and adaptive responses are dependent on precursor frequency of lymphocytes, antigenic dose and mode of exposure. Studies in neonatal mouse models and human umbilical cord blood cells demonstrate the capability of neonatal immune cells to produce immune responses similar to adults in some aspects but not others. This review focuses mainly on the developmental and functional mechanisms of the human neonatal immune system. In particular, the mechanism of innate and adaptive immunity and the role of neutrophils, antigen presenting cells, differences in subclasses of T lymphocytes (Th1, Th2, Tregs) and B cells are discussed. In addition, we have included the recent developments in the neonatal mouse immune system. Understanding neonatal immunity is essential to development of therapeutic vaccines to combat newly emerging infectious agents.

Commonality of the IL-4/IL-13 pathway in atopic diseases

Abstract: Introduction: Allergy results from an aberrant Type 2 inflammatory response, triggered by a wide range of environmental antigens (allergens) that lead to various immune responses, culminating in the production of immunoglobulin E (IgE). Two key cytokines, interleukin (IL)-4 and IL-13, are critical to the induction and perpetuation of the Type 2 response, and have been implicated in multiple atopic diseases.Area covered: This review summarizes recent milestone developments that have elucidated components of the pathogenesis of atopic diseases such as atopic dermatitis (AD), asthma, and chronic sinusitis with nasal polyposis (CSwNP).Expert commentary: Several therapeutic agents that selectively target potentiators of the Type 2 pathway have shown efficacy in one or more of these atopic diseases, but few agents have proven to be broadly applicable across all three atopic diseases. Dupilumab, a human monoclonal antibody that simultaneously inhibits signaling of IL-4 and IL-13, has demonstrated signifi...

The current understanding of Stevens-Johnson syndrome and toxic epidermal necrolysis

Abstract: Stevens-Johnson syndrome has long been considered to resemble erythema multiforme with mucosal involvement, but is now thought to form a single disease entity with toxic epidermal necrolysis. Although Stevens-Johnson syndrome is less severe, etiology, genetic susceptibility and pathomechanism are the same for Stevens-Johnson syndrome/toxic epidermal necrolysis. The condition is mainly caused by drugs, but also by infections and probably other risk factors not yet identified. Identification of the cause is important for the individual patient and in cases of drug-induced disease withdrawal of the inducing drug(s) has an impact on the patient's prognosis. If an infectious cause is suspected, adequate anti-infective treatment is needed. Besides this, supportive management is crucial to improve the patient's state, probably more than specific immunomodulating treatments. Despite all of the therapeutic efforts, mortality is high and increases with disease severity, patients' age and underlying medical conditions. Survivors may suffer from long-term sequelae such as strictures of mucous membranes including severe eye problems.

Medication adherence in patients with rheumatoid arthritis: a critical appraisal of the existing literature.

Abstract: Adherence to medication in patients with rheumatoid arthritis is low, varying from 30 to 80%. Improving adherence to therapy could therefore dramatically improve the efficacy of drug therapy. Although indicators for suboptimal adherence can be useful to identify nonadherent patients, and could function as targets for adherence-improving interventions, no indicators are yet found to be consistently and strongly related to nonadherence. Despite this, nonadherence behavior could conceptually be categorized into two subtypes: unintentional (due to forgetfulness, regimen complexity or physical problems) and intentional (based on the patient's decision to take no/less medication). In case of intentional nonadherence, patients seem to make a benefit-risk analysis weighing the perceived risks of the treatment against the perceived benefits. This weighing process may be influenced by the patient's beliefs about medication, the patient's self-efficacy and the patient's knowledge of the disease. This implicates that besides tackling practical barriers, clinicians should be sensitive to patient's personal beliefs that may impact medication adherence.
