Non-classical B Cell Memory of Allergic IgE Responses

Non-classical B Cell Memory of Allergic IgE Responses Sean P. Saunders1, Erica G. M. Ma1,2, Carlos J. Aranda1 and Maria A. Curotto de Lafaille1,3* 1Division of Pulmonary, Critical Care and Sleep Medicine, Laboratory of Allergy and Inflammation, Department of Medicine, New York University, New York, NY, United States 2Sackler Institute of Graduate Biomedical Sciences, New York University, New York, NY, United States 3Department of Cell Biology, New York University School of Medicine, New York, NY, United States The long-term effectiveness of antibody responses relies on the development of humoral immune memory. Humoral immunity is maintained by long-lived plasma cells that secrete antigen-specific antibodies, and memory B cells that rapidly respond to antigen re-exposure by generating new plasma cells and memory B cells. Developing effective immunological memory is essential for protection against pathogens, and is the basis of successful vaccinations. IgE responses have evolved for protection against helminth parasites infections and against toxins, but IgE is also a potent mediator of allergic diseases. There has been a dramatic increase in the incidence of allergic diseases in recent decades and this has provided the impetus to study the nature of IgE antibody responses. As will be discussed in depth in this review, the IgE memory response has unique features that distinguish it from classical B cell memory. General Mechanisms of Humoral Memory in Mice and H...

Authors: Peng C, Cohen DJ Abstract INTRODUCTION: Esophageal squamous cancer remains an important cause of mortality worldwide with two new immunotherapy drugs recently approved for metastatic disease. AREAS COVERED: The authors review the epidemiology and genomics of esophageal squamous cell carcinoma. They also examine prior trials involving targeted agents under investigation as well immunotherapies that have been approved and novel combinations. EXPERT OPINION: Great advances have been made in characterizing the molecular changes in esophageal carcinoma. However, relatively few drugs have shown benefit i...

This article summarizes the rationale for, and development of CDK inhibitors in melanoma, with their evolution from pan-CDK inhibitors to highly specific agents, throughout clinical trials and finally their potential future use. EXPERT OPINION: Whilst CDK inhibitors have been practice changing in breast cancer management, their efficacy is yet to be proven in melanoma. Combination with BRAF/MEK inhibitors has been hindered by dose-limiting toxicities, but their role may yet to be found within the spectrum of biomarker-derived personalized melanoma management. The effect that CDK inhibitors can have as an adjunct to imm...

Abstract Trace metals concentrations of 25 elements were determined for 22 subcomponents of biodegradable and non-biodegradable waste samples representing the United States municipal solid waste (MSW) stream collected during three separate waste sorts. The subcomponent trace metal concentrations and estimated composition results were used to predict trace metal concentrations present in the overall MSW stream along with MSW compost and waste to energy (WTE) ash, which were compared to health-based standards (i.e., US EPA regional screening levels) and to values previously reported in the literature. These estimate...
