Component‐resolved diagnosis of wasp (yellow jacket) venom allergy
ConclusionComponent‐resolved diagnoses with the wasp‐specific recombinant allergen components Ves v 1 and Ves v 5 is a reliable method to diagnose yellow jacket allergy and can help to take out the sting of difficult cases. However, as the number of patients with doubt after conventional tests is small, larger collaborative studies are needed to draw more definitive conclusions. Whether the rVes v 5 supplemented yellow jacket allergosorbent constitutes an asset in the diagnostic management of wasp venom allergy remains to be further established.

Production of Serotonin by Tryptophan Hydroxylase 1 andRelease via Platelets Contribute to Allergic Airway Inflammation.
CONCLUSION: In summary, TPH1-deficiency or -inhibition reduces AAI. Platelet- and not mast cell-derived 5-HT is pivotal in AAI, and lack of 5-HT leads to an impaired Th2-priming capacity of BMDC. Thus, targeting TPH1 could offer novel therapeutic options for asthma. PMID: 23328530 [PubMed - as supplied by publisher]

Molecular Control of Steady-State Dendritic Cell Maturation and Immune Homeostasis.
Abstract Dendritic cells (DCs) are specialized sentinels responsible for coordinating adaptive immunity. This function is dependent upon coupled sensitivity to environmental signs of inflammation and infection to cellular maturation-the programmed alteration of DC phenotype and function to enhance immune cell activation. Although DCs are thus well equipped to respond to pathogens, maturation triggers are not unique to infection. Given that immune cells are exquisitely sensitive to the biological functions of DCs, we now appreciate that multiple layers of suppression are required to restrict the environmental sensit...

The majority of T cells, including T(reg) cells, are developed from CD4(-)CD8(-) T progenitor cells without the involvement of the CD4(+)CD8(+) stage in the thymus.
In this study, we examined CD4(-)CD8(-) (DN) cells as precursors of T cells. We provided evidence that DN-CD25(+) T cells could express the gene encoding forkhead box P3 (Foxp3) at high levels but were unable to express genes for T cell receptor (TCR) and cluster of differentiation 3 (CD3). In contrast, DN-CD25(-) cells could express and produce TCR and CD3 but not Foxp3. Furthermore, DN cells exhibited a higher-level expression of cell surface marker CD25, as well as Foxp3, but reduced expression of CD44, CD3, and TCR when compared to CD4(+)CD8(-) T cells. In the process of T cell development in the thymus, we noted that ...

The immune system's involvement in obesity-driven type 2 diabetes.
Abstract Type 2 diabetes is now a worldwide epidemic, strongly correlated with an elevated incidence of obesity. Obesity-associated adipose tissue inflammation is a major cause of the decreased insulin sensitivity seen in type 2 diabetes. Recent studies have shed light on the cross-talk between the immune system and organismal metabolism. This review discusses the connection between inflammation in adipose tissue and systemic insulin resistance, focusing on the roles of innate and adaptive immune cell subsets in the pathogenesis of this metabolic disease.

Dendritic cells administered intrarectally penetrate the intestinal barrier to break intestinal tolerance via Th2-medeiated colitis in mice.
Abstract Intestinal lamina propria dendritic cells (LPDCs) in mice are known to extend dendrites between the intestinal epithelia and the luminal side when processing luminal antigens. We conducted intrarectal cell transfer experiments of bone marrow-derived dendritic cells (BMDCs) in mice to assess dendritic cell penetration of the intestine. Intrarectally administered GFP(+) BMDCs localized in the colonic LP within 3h and the spleen within 12h after administration. 72h after administration, recipient C57BL/6 mice showed acute diarrhea, and administration of BMDCs (once weekly for 3 week) induced intestinal inflam...

Guidelines for the use of human immunoglobulin therapy in patients with primary immunodeficiencies in Latin America.
Abstract Antibodies are an essential component of the adaptative immune response and hold long-term memory of the immunological experiences throughout life. Antibody defects represent approximately half of the well-known primary immunodeficiencies requiring immunoglobulin replacement therapy. In this article, the authors review the current indications and therapeutic protocols in the Latin American environment. Immunoglobulin replacement therapy has been a safe procedure that induces dramatic positive changes in the clinical outcome of patients who carry antibody defects.

Maintenance of Host Leukocytes in Peripheral Immune Compartments Following Lethal Irradiation and Bone Marrow Reconstitution: Implications for Graft Versus Host Disease.
Abstract Bone marrow reconstitution is utilized as a tool for disease treatment and as a research technique to elucidate the function of bone marrow derived cells. Clinically successful engraftment is indicated by the development of a functioning immune repertoire. In research, reconstitution is considered successful if >85% of splenic leukocytes are of donor origins. Previous work suggests that splenic reconstitution may not be indicative of reconstitution in the mucosa. We sought to evaluate mucosal reconstitution in animals following a standard bone marrow eradication and reconstitution technique. Bone marrow...

KCNE gene expression is dependent on the proliferation and mode of activation of leukocytes.
Abstract Voltage-dependent K (+) (Kv) channels are tightly regulated during the immune system response. Leukocytes have a limited repertoire of Kv channels, whose physiological role is under intense investigation. A functional Kv channel is an oligomeric complex composed of pore-forming and ancillary subunits. The KCNE gene family is a novel group of modulatory Kv channel elements in leukocytes. Here, we characterized the gene expression of KCNEs (1-5) in leukocytes and investigated their regulation during leukocyte proliferation and mode of activation.

Human cytomegalovirus particles directly suppress CD4 T-lymphocyte activation and proliferation.
In this study, we found that HCMV directly inhibited proliferation of CD4 T cells and rendered them unresponsive to immunological stimuli. This effect was not observed when CD4 T cells were treated with herpes simplex virus-1/2 or measles virus. When stimulated with phytohemagglutinin, concanavalin A, or phorbol myristate acetate, HCMV-treated T cells were unable to proliferate, revealing an ability of HCMV to inhibit CD4 T cell response. Furthermore, HCMV also prevented proliferation of leukemic T-cell lines. HCMV-treated CD4 T cells expressed the activation markers CD45RO and CD69, were not apoptotic and produced decreas...

Gastroesophageal Reflux Disease in Neonates and Infants : When and How to Treat.
Abstract Gastroesophageal reflux (GER) is defined as the involuntary retrograde passage of gastric contents into the esophagus with or without regurgitation or vomiting. It is a frequently experienced physiologic condition occurring several times a day, mostly postprandial and causes no symptoms. These infants are also called 'happy spitters'. GER disease (GERD) occurs when reflux of the gastric contents causes symptoms that affect the quality of life or pathologic complications, such as failure to thrive, feeding or sleeping problems, chronic respiratory disorders, esophagitis, hematemesis, apnea, and apparent lif...

The autoimmune-predisposing variant of lymphoid tyrosine phosphatase favors T helper 1 responses.
Abstract The C1858T single nucleotide polymorphism in PTPN22, which is the gene encoding lymphoid tyrosine phosphatase (LYP), confers increased risk for various autoimmune disorders in Caucasians. Although the disease-associated LYP allele (LYP∗W620) is a gain-of-function variant that has higher catalytic activity than the major allele (LYP∗R620), it is still unclear how LYP∗W620 predisposes for autoimmunity. Here, we compared both T cell signaling and T cell function in healthy human donors homozygous for either LYP∗R620 or LYP∗W620. Generally, the presence of LYP∗W620 caused reduced proximal T cell an...
