(2016). Development of a recombinant immunotoxin for the immunotherapy of autoreactive lymphocytes expressing MOG-specific BCRs. Biotechnol. Lett. , [+]

    Myelin oligodendrocyte glycoprotein (MOG) is one of the major autoantigens in multiple sclerosis (MS), therefore selective depletion of autoreactive lymphocytes exposing MOG-specific B cell receptors (BCRs) would be beneficial in terms of MS treatment.

    We report a new surface modification approach of upconversion nanoparticles (UCNPs) structured as inorganic hosts NaYF4 codoped with Yb(3+) and Er(3+) based on their encapsulation in a two-stage process of precipitation polymerization of acrolein under alkaline conditions in the presence of UCNPs. The use of tetramethylammonium hydroxide both as an initiator of acrolein polymerization and as an agent for UCNP hydrophilization made it possible to increase the polyacrolein yield up to 90%. This approach enabled the facile, lossless embedment of UCNPs into the polymer particles suitable for bioassay. These particles are readily dispersible in aqueous and physiological buffers, exhibiting excellent photoluminescence properties, chemical stability, and also allow the control of particle diameters. The feasibility of the as-produced photoluminescent polymer particles mean-sized 260 nm for in vivo optical whole-animal imaging was also demonstrated using a home-built epi-luminescence imaging system.

Cytotoxicity and non-specific cellular uptake of bare and surface-modified upconversion nanoparticles in human skin cells. Nano Research 8 (5), 1546–1562 [+]

    The cytotoxicity and non-specific cellular uptake of the most popular composition of upconversion nanoparticle (UCNP), NaYF4:Yb3+:Er3+, is reported using normal human skin cells, including dermal fibroblasts and immortalized human epidermal linear keratinocytes (HaCaT). A new hydrophilization reaction of as-synthesized UCNPs based on tetramethylammonium hydroxide (TMAH) enabled evaluation of the intrinsic cytotoxicity of bare UCNPs. The cytotoxicity effects of the UCNP surface-coating and polystyrene host were investigated over the concentration range 62.5–125 μg/mL with 24-h incubation, using a MTT test and optical microscopy. The fibroblast viability was not compromised by UCNPs, whereas the viability of keratinocytes varied from 52% ± 4% to 100% ± 10% than the control group, depending on the surface modification. Bare UCNPs reduced the keratinocyte viability to 76% ± 3%, while exhibiting profound non-specific cellular uptake. Hydrophilic poly(D,L-lactide)- and poly(maleic anhydride-alt-1-octadecene)-coated UCNPs were found to be least cytotoxic among the polymer-coated UCNPs, and were readily internalized by human skin cells. Polystyrene microbeads impregnated with UCNPs remained nontoxic. Surprisingly, no correlation was found between UCNP cytotoxicity and the internalization level in cells, although the latter ranged broadly from 0.03% to 59%, benchmarked against 100% uptake level of TMAH-UCNPs.

    The E. coli strain, overproducing human growth hormone (hGH) was made by integration of the hGH gene under the control of T7 promoter into the chromosomal LacZ gene of BL21(DE3) via lambda Red recombineering. The strain gave higher productivity (50 mg·L(-1)·OD550(-1)) and better growth characteristics than the corresponding strain in which the same hGH expression cassette was placed in a plasmid. The protein produced by the plasmid-free strain was purified and characterized to be hGH. The results demonstrates that a plasmid-free recombinant strain having a single-copy gene expression cassette in the chromosome could provide better gene activity regulation, higher productivity, superior growth characteristics, as well as more stringent control of the gene sequence invariance than a plasmid-based strain.
