Inclusion of non-target antigen in vaccination favors generation of OVA specific CD4 memory T cells.

Cell Immunol 2018 Nov 19. Epub 2018 Nov 19.

Institute of Science, Nirma University, Ahmedabad, Gujarat, India. Electronic address:

Inducing long-lived memory T cells by sub-unit vaccines has been a challenge. Subunit vaccines containing single immunogenic target antigen from a given pathogen have been designed with the presumption of mimicking the condition associated with natural infection, but fail to induce quality memory responses. In this study, we have included non-target antigens with vaccine candidate, OVA, in the inoculum containing TLR ligands to suffice the minimal condition of pathogen to provoke immune response.

Biological activities of interleukin (IL)-21 in human monocytes and macrophages.

Cell Immunol 2019 Feb 8. Epub 2019 Feb 8.

Laboratoire de recherche en inflammation et physiologie des granulocytes, Université du Québec, INRS-Institut Armand-Frappier, Laval, Québec, Canada. Electronic address:

The biological roles of interleukin (IL)-21 in human monocytes and macrophages have been neglected. We previously demonstrated that IL-21 induce phagocytosis and established that Syk is a new molecular target of IL-21. Herein, we found that IL-21 is not chemoattractant for immature THP-1 and primary monocytes but can increase the capacity of THP-1 cells (not primary monocytes) to adhere onto a cell substratum by a Syk-dependent mechanism without altering the expression of a panel of cell surface molecules.

ER-stress regulates macrophage polarization through pancreatic EIF-2alpha kinase.

Cell Immunol 2019 Feb 21;336:40-47. Epub 2018 Dec 21.

Department of Hepatobiliary Surgery, Affiliated Drum Tower Hospital of Nanjing University Medical School, 321, Zhongshan Road, 210008 Nanjing, Jiangsu Province, China. Electronic address:

During the process of NAFLD progression, ER-stress is activated in macrophages and induces the pro-inflammatory polarization of macrophage. As one of the three ER membrane resident proteins, pancreatic eIF-2alpha kinase (PERK) plays an important role in ER stress, but its participation in macrophage polarization is largely unknown. In this study, we found that the PA mediated ER-stress activation could induce M1-type polarization in macrophages, and this phenotype polarization could be inhibited by ER-stress inhibitor 4-PBA as well as GSK2656157, an inhibitor of PERK.

Translational Research Program, Benaroya Research Institute at Virginia Mason, Seattle, WA 98101, USA. Electronic address:

CD4+ T cell responses are thought to play a role in type 1 diabetes (T1D). However, detection and characterization of T cells that respond to beta cell epitopes in subjects with T1D has been limited by technical obstacles, including the inherently low frequencies in peripheral blood and variable responsiveness of individual subjects to single epitopes. We implemented a multicolor staining approach that allows direct ex vivo characterization of multiple CD4+ T cell specificities in a single sample. Read More

Intracellular and extracellular effector activity of mouse neutrophils in response to cutaneous and visceral Leishmania parasites.

Cell Immunol 2019 Jan 7;335:76-84. Epub 2018 Nov 7.

Global Health and Tropical Medicine, GHTM, Instituto de Higiene e Medicina Tropical, IHMT, Universidade Nova de Lisboa, UNL. Rua da Junqueira 100, 1349-008 Lisboa, Portugal. Electronic address:

Neutrophils are short-lived phagocytic cells equipped with several receptors for pathogen recognition and phagocytosis and have intracellular and extracellular effector mechanisms that can inactivate pathogens. Leishmaniases are diseases caused by different species of Leishmania that mainly afflicts poorer populations of tropical and subtropical regions and immunocompromised individuals. Thus, the present study aims to investigate the effector response of murine neutrophils to species of Leishmania causing American cutaneous leishmaniasis and zoonotic visceral leishmaniasis by evaluating pattern recognition receptors (PRR) and intracellular and extracellular effector microbicide activity.

The airway mucosa is the primary tissue site exposed to inhaled particulate matter, which includes pathogens and allergens. While most inhaled particles are eliminated from the airways via mucociliary clearance, some pathogens may penetrate the mucosal epithelial barrier and an effective activation of the mucosal immune system is required to prevent further pathogen spread. Similarly, inhaled environmental allergens may induce an aberrant activation of immune cells in the airway mucosa, causing allergic airway disease. Read More

A large number of animal models revealed that IL-3 plays an important role for the development of T and B cell-mediated autoimmune diseases. However, little is known about the expression and regulation of IL-3 receptors in human T and B cells and how IL-3 modulates the activation and survival of these cells. We show that the IL-3 receptor CD123 is substantially upregulated on proliferating CD4 and CD8 T as well as B cells. Read More
