Epstein-Barr Virus-Associated γδ T-Cell Lymphoproliferative Disorder Associated With Hypomorphic Mutation.

Front Pediatr 2019 4;7:15. Epub 2019 Feb 4.

Department of Child Health and Development, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University, Tokyo, Japan.

Chronic active Epstein-Barr virus (EBV) infection (CAEBV) is an EBV-associated lymphoproliferative disease characterized by repeated or sustainable infectious mononucleosis (IM)-like symptoms. EBV is usually detected in B cells in patients who have IM or Burkitt's lymphoma and even in patients with X-linked lymphoproliferative syndrome, which is confirmed to have vulnerability to EBV infection. In contrast, EBV infects T cells (CD4 T, CD8 T, and γδT) or NK cells mono- or oligoclonally in CAEBV patients. Read More

Danger signals in oral cavity-related diseases.

J Leukoc Biol 2019 Feb 18. Epub 2019 Feb 18.

Department of Oral Biology, School of Dental Medicine, University at Buffalo, Buffalo, New York, USA.

The oral cavity is a unique environment containing teeth juxtaposed with soft tissues, all of which are constantly bathed in microbial products and host-derived factors. While microbial dysbiosis in the oral cavity clearly leads to oral inflammatory disease, recent advances find that endogenous danger-associated molecular patterns (DAMPs) released from oral and salivary tissue also contribute to the progression of inflammatory and autoimmune disease, respectively. In contrast, DAMPs produced during oral fungal infection actually promote the resolution of infection. Read More

Pro-inflammatory agents released by pathogens, dying host cells, and neutrophils act synergistically to destroy host tissues: a working hypothesis.

J Inflamm Res 2019 23;12:35-47. Epub 2019 Jan 23.

Department of Pathology, The University of Michigan Medical School, Ann Arbor, MI, USA.

We postulate that the extensive cell and tissue damage inflicted by many infectious, inflammatory and post-inflammatory episodes is an enled result of a synergism among the invading microbial agents, host neutrophils and dead and dying cells in the nidus. Microbial toxins and other metabolites along with the plethora of pro-inflammatory agents released from activated neutrophils massively recruited to the infectious sites and high levels of cationic histones, other cationic peptides, proteinases and Th1 cytokines released from activated polymorphonuclear neutrophils (PMNs) and from necrotized tissues may act in concert (synergism) to bring about cell killing and tissue destruction. Multiple, diverse interactions among the many potential pro-inflammatory moieties have been described in these complex lesions. Read More

Morphological and functional analysis of beige (Chèdiak-Higashi syndrome) mouse mast cells with giant granules.

Int Immunopharmacol 2019 Feb 6;69:202-212. Epub 2019 Feb 6.

Department of Pharmacology, Ehime University Graduate School of Medicine Shitsukawa, Toon, Ehime 791-0295, Japan.

Chèdiak-Higashi syndrome is a rare autosomal recessive disease that causes hypopigmentation, recurrent infections, mild coagulation defects and neurological problems. Beige mice carry a mutation in the lysosome trafficking regulator (LYST) gene and display some of the key characteristics of human Chèdiak-Higashi syndrome, in particular, a high susceptibility to infection due to aberrant natural killer (NK) cell and polymorphonuclear leucocyte function. Morphological analysis of beige mice reveals the presence of enlarged lysosomes in a variety of cell types, including leucocytes, hepatocytes, fibroblasts and renal tubule cells. Read More

A case report of severe recurrent varicella in an ankylosing spondylitis patient treated with adalimumab - a new side effect after 15 years of usage.

BMC Infect Dis 2019 Feb 7;19(1):127. Epub 2019 Feb 7.

University Hospital for Infectious Diseases "Dr. Fran Mihaljević", Mirogojska 8, 10000, Zagreb, Croatia.

Background: Tumor necrosis factor-α (TNF-α) antagonists, most of which are monoclonal antibodies, became a widespread treatment for autoimmune diseases such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel diseases, psoriasis, psoriatic arthritis, hidradenitis suppurativa and uveitis. Their use is based on the blockage of TNF-α, which plays an important role in granulomas formation, development of phagosomes, activation and differentiation of macrophages, immune response against viral pathogens. The multiple adverse effects of TNF-α inhibition have been identified, including a two-to four-fold increased risk of active tuberculosis and other granulomatous conditions and an increased occurrence of some other serious bacterial, fungal and certain viral infections.

PIKfyve/Fab1 is required for efficient V-ATPase and hydrolase delivery to phagosomes, phagosomal killing, and restriction of Legionella infection.

PLoS Pathog 2019 Feb 7;15(2):e1007551. Epub 2019 Feb 7.

Centre for Membrane Interactions and Dynamics, Department of Biomedical Sciences, University of Sheffield, Firth Court, Western Bank, Sheffield, United Kingdom.

By engulfing potentially harmful microbes, professional phagocytes are continually at risk from intracellular pathogens. To avoid becoming infected, the host must kill pathogens in the phagosome before they can escape or establish a survival niche. Here, we analyse the role of the phosphoinositide (PI) 5-kinase PIKfyve in phagosome maturation and killing, using the amoeba and model phagocyte Dictyostelium discoideum. Read More

An update on possible pathogenic mechanisms of periodontal pathogens on renal dysfunction.

Crit Rev Microbiol 2019 Feb 7:1-25. Epub 2019 Feb 7.

b Department of Prosthodontics, Manipal College of Dental Sciences , Manipal Academy of Higher Education , Manipal , Karnataka , India.

Periodontitis is a potential source of permanent systemic inflammation that initiates renal dysfunction and contributes to the development of chronic kidney diseases (CKDs). Although numerous studies have confirmed the bidirectional role of periodontal infection and renal inflammation, no literature has yet highlighted the sophisticated pathogenic mechanisms by which periodontal pathogens, particularly Porphynomonas Gingivalis, induce renal dysfunction and contributed in the development of CKDs. The present review aims to critically analyze and highlight the novel pathogenesis of periodontitis induced CKDs. Read More

Macrophage β2-Integrins Regulate IL-22 by ILC3s and Protect from Lethal Citrobacter rodentium-Induced Colitis.

Cell Rep 2019 Feb;26(6):1614-1626.e5

Department of Microbiology, University of Pennsylvania School of Dental Medicine, Philadelphia, PA 19104, USA. Electronic address:

β2-integrins promote neutrophil recruitment to infected tissues and are crucial for host defense. Neutrophil recruitment is defective in leukocyte adhesion deficiency type-1 (LAD1), a condition caused by mutations in the CD18 (β2-integrin) gene. Using a model of Citrobacter rodentium (CR)-induced colitis, we show that CD18 mice display increased intestinal damage and systemic bacterial burden, compared to littermate controls, ultimately succumbing to infection.
