Fine Tuning A Well-Oiled Machine: Influence Of Nk1.1 And Nkg2d On Nkt Cell Development And Function, Sunil K. Joshi, Mark L. Lang

Bioelectrics Publications

Natural killer T cells (NKT) represent a group of CD1d-restricted T-lineage cells that provide a functional interface between innate and adaptive immune responses in infectious disease, cancer, allergy and autoimmunity. There have been remarkable advances in understanding the molecular events that underpin NKT development in the thymus and in the complex array of functions in the periphery. Most functional studies have focused on activation of T cell antigen receptors expressed by NKT cells and their responses to CD1d presentation of glycolipid and related antigens. Receiving less attention has been several molecules that are hallmarks of Natural Killer (NK) cells, but …

Evaluation Of A Novel Rapid Diagnostic Test For Schistosoma Haematobium Based On The Detection Of Human Immunoglobulins Bound To Filtered Schistosoma Haematobium Eggs, Johnathan M. Sheele, Jimmy H. Kihara, Sarah Baddorf, Jonathan Byrne, Bhaskara Ravi

Objectives To determine whether the detection of human IgG bound to Schistosoma haematobium eggs from filtered urine could be used as a rapid diagnostic test (RDT-Sh).

Methods We filtered 160 urine samples from children in the Kwale District of Kenya to isolate S.haematobium eggs and used anti-human IgG antibody conjugated to horseradish peroxidase to bind to the human IgG attached to the eggs. We then added 3,35,5-tetramethylbenzidine base (TMB), which turns blue in the presence of horseradish peroxidase to detect the S.haematobium eggs. The RDT-Sh was compared in a blinded manner to urine microscopy.

Results The RDT-Sh was positive in …

Study Of Charge-Dependent Transport And Toxicity Of Peptide-Functionalized Silver Nanoparticles Using Zebrafish Embryos And Single Nanoparticle Plasmonic Spectroscopy, Kerry J. Lee, Lauren M. Browning, Prakash D. Nallathamby, Xiao-Hong Nancy Xu

Chemistry & Biochemistry Faculty Publications

Nanomaterials possess unusually high surface area-to-volume ratios and surface-determined physicochemical properties. It is essential to understand their surface-dependent toxicity in order to rationally design biocompatible nanomaterials for a wide variety of applications. In this study, we have functionalized the surfaces of silver nanoparticles (Ag NPs, 11.7 ±+2.7 nm in diameter) with three biocompatible peptides (CALNNK, CALNNS, CALNNE) to prepare positively (Ag-CALNNK NPs^+ζ), negatively (Ag-CALNNS NPs^−2ζ), and more negatively charged NPs (Ag-CALNNE NPs^−4ζ), respectively. Each peptide differs in a single amino acid at its C-terminus, which minimizes the effects of peptide sequences and serves as …
