Thymic regulatory T cells arise via two distinct developmental programs.

Nat Immunol 2019 Feb 14;20(2):195-205. Epub 2019 Jan 14.

Center for Immunology, Masonic Cancer Center, and the Department of Laboratory Medicine and Pathology, University of Minnesota, Minneapolis, MN, USA.

The developmental programs that generate a broad repertoire of regulatory T cells (T cells) able to respond to both self antigens and non-self antigens remain unclear. Here we found that mature T cells were generated through two distinct developmental programs involving CD25 T cell progenitors (CD25 TP cells) and Foxp3 T cell progenitors (Foxp3 TP cells). CD25 TP cells showed higher rates of apoptosis and interacted with thymic self antigens with higher affinity than did Foxp3 TP cells, and had a T cell antigen receptor repertoire and transcriptome distinct from that of Foxp3 TP cells.

A quantitative risk assessment (QRA) of the risk of introduction of the Japanese encephalitis virus (JEV) in the United States via infected mosquitoes transported in aircraft and cargo ships.

Prev Vet Med 2018 Nov 24;160:1-9. Epub 2018 Sep 24.

Department of Diagnostic Medicine and Pathobiology, College of Veterinary Medicine, Kansas State University, Manhattan, Kansas, 66506, United States. Electronic address:

Following a qualitative risk assessment, in which we identified and assessed all viable pathways for the introduction of the Japanese encephalitis virus (JEV) into the United States (US), we identified entry through infected vectors via aircraft and cargo ships as the most likely pathway, and thus considered it further in a quantitative risk assessment (QRA) model. The objective of this study was to evaluate the risk of introduction of JEV in the US via infected mosquitoes transported in aircraft and cargo ships arriving from Asia, using a QRA model. We created a stochastic model to quantify the probability of introduction of at least one infected mosquito in the continental US via aircraft and cargo ships, per at-risk period (March to October) or year, respectively.

Department of Molecular Medicine, University of Padova, via A. Gabelli 63, 35121, Padova, Italy. Electronic address:

During the last decades, arboviruses that are endemic in Europe have expanded their geographic range and caused an increasing number of human outbreaks. These viruses include West Nile virus, which is expanding its area of circulation in central and southern Europe; Usutu virus, with increasing evidence of a role in human disease; tick-borne encephalitis virus, which is being detected in northern areas and at higher altitudes as a consequence of climate warming; Crimean-Congo hemorrhagic fever virus, which is endemic in Eastern Europe and the Middle East, but has been recently detected in Spain; other viruses, such as California encephalitis virus antigenic group, which circulate in northern and central Europe but whose relevance for human disease in largely unknown. In addition, the rise in global travel and trade has posed Europe to an increased risk of introduction and expansion of exotic arthropod vectors and autochthonous transmission of arboviruses, like dengue and chikungunya viruses, following new introductions from endemic areas.

Determination of system level alterations in host transcriptome due to Zika virus (ZIKV) Infection in retinal pigment epithelium.

Sci Rep 2018 Jul 25;8(1):11209. Epub 2018 Jul 25.

BIDMC Genomics, Proteomics, Bioinformatics and Systems Biology Centre, Beth Israel Deaconess Medical Center, Boston, MA, USA.

Previously, we reported that Zika virus (ZIKV) causes ocular complications such as chorioretinal atrophy, by infecting cells lining the blood-retinal barrier, including the retinal pigment epithelium (RPE). To understand the molecular basis of ZIKV-induced retinal pathology, we performed a meta-analysis of transcriptome profiles of ZIKV-infected human primary RPE and other cell types infected with either ZIKV or other related flaviviruses (Japanese encephalitis, West Nile, and Dengue). This led to identification of a unique ZIKV infection signature comprising 43 genes (35 upregulated and 8 downregulated). Read More

Safety of repeated doses of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine in adults and adolescents.

Pharmacoepidemiol Drug Saf 2018 Aug 3;27(8):921-925. Epub 2018 Jun 3.

Kaiser Permanente Washington Health Research Institute, Seattle, WA, USA.

In light of waning immunity to pertussis following receipt of tetanus toxoid, reduced diphtheria toxoid and acellular pertussis (Tdap) vaccine, maintaining protection may require repeated Tdap vaccination. We evaluated the safety of repeated doses of tetanus-containing vaccine in 68 915 nonpregnant adolescents and adults in the Vaccine Safety Datalink population who had received an initial dose of Tdap. Compared with 7521 subjects who received a subsequent dose of tetanus toxoid, reduced diphtheria (Td) vaccine, the 61 394 subjects who received a subsequent dose of Tdap did not have significantly elevated risk of medical visits for seizure, cranial nerve disorders, limb swelling, pain in limb, cellulitis, paralytic syndromes, or encephalopathy/encephalitis/meningitis.

Ovarian teratoma associated Anti-N-methyl-D-aspartate receptor encephalitis: a difficult diagnosis with a favorable prognosis.

Autops Case Rep 2018 Apr-Jun;8(2):e2018019. Epub 2018 Apr 18.

University of California, Davis Medical Center, Department of Pathology and Laboratory Medicine . Sacramento, CA , USA .

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a recently described auto-immune and paraneoplastic encephalitis with prominent neuropsychiatric manifestations affecting young adults with ovarian teratoma. The availability of a novel assay to measure these antibodies might suggest an etiology for this potentially life-threatening disease, which if early recognized can be treated promptly with surgery with chances of a good clinical outcome. Reported prognostic indicators for a good outcome depend on the presence of a tumor, prompt treatment and no admission to an intensive care unit. Read More
