Abstract
Herein, an advanced bioconjugation technique to synthesize hybrid polymer-antibody nanoprobes tailored for fluorescent cell barcoding in flow cytometry-based immunophenotyping of leukocytes is applied. A novel approach of attachment combining two fluorescent dyes on the copolymer precursor and its conjugation to antibody is employed to synthesize barcoded nanoprobes of antibody polymer dyes allowing up to six nanoprobes to be resolved in two-dimensional cytometry analysis. The major advantage of these nanoprobes is the construct design in which the selected antibody is labeled with an advanced copolymer bearing two types of fluorophores in different molar ratios. The cells after antibody recognition and binding to the target antigen have a characteristic double fluorescence signal for each nanoprobe providing a unique position on the dot plot, thus allowing antibody-based barcoding of cellular samples in flow cytometry assays. This technique is valuable for cellular assays that require low intersample variability and is demonstrated by the live cell barcoding of clinical samples with B cell abnormalities. In total, the samples from six various donors were successfully barcoded using only two detection channels. This barcoding of clinical samples enables sample preparation and measurement in a single tube.

A new construct of antibody-drug conjugates for treatment of B-cell non-Hodgkin's lymphomas. Eur J Pharm Sci 2017; 103:36-46.

Abstract
The aim of this study was to develop a new class of antibody-drug conjugates (ADCs) with the potential to not only enhance treatment efficacy but also improve tolerability for patients with B-cell lymphomas. Classic ADCs consist of monoclonal antibodies (mAbs) linked to drugs or toxins. They selectively deliver toxic moieties to tumor cells. As such, they greatly improve the therapeutic index compared to traditional chemotherapeutic agents. However, the therapeutic efficacy and safety of ADCs are dependent on linker stability and payload toxicity. Limited payload number on a single antibody (drug-to-antibody ratio, or DAR) has been driving investigators to use extremely toxic agents; however, even very low off-target binding of these ADCs may kill patients. Herein we report a new design of ADCs that consists of rituximab (RTX) and N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer-epirubicin conjugates. The latter was selectively attached to RTX via reduced disulfide bonds. Such design allows the introduction of a large payload of drug on the antibody without adding attachment sites and without compromising the antigen-targeting ability. The binding of the new conjugate, namely RTX-P-EPI, to Ramos cells (with high CD20 expression) was confirmed. The cytotoxicity of RTX-P-EPI against Raji and Ramos cells was also determined. Interestingly, two-fold inhibition of cell proliferation was observed when using RTX-P-EPI compared with their equivalent physical mixture of RTX and P-EPI. Treatment of male SCID mice bearing subcutaneous Ramos B-cell lymphoma tumors demonstrated that RTX-P-EPI possessed superior efficacy when compared to combination of RTX with chemotherapy EPI (RTX+EPI) and P-EPI (RTX+P-EPI), whereas single RTX and a non-specific conjugate IgG-P-EPI only showed marginal effect. The conjugate RTX-EPI in which EPI was directly attached to RTX demonstrated much less antitumor activity compared with RTX-P-EPI. The results suggest that this new design possesses synergistic potential of immunotherapy combined with established macromolecular therapy; moreover, a conventional chemo-agent could be utilized to generate highly effective ADCs and to achieve lower risk of off-target toxicity.

Abstract
During the last 3 decades, nanomedicines have provided novel opportunities to improve the delivery of chemotherapeutics in cancer therapy effectively. However, many principles learnt from there have the potential to be transferred to other diseases. This perspective article, on the one hand, critically reflects the limitations of nanomedicines in tumor therapy and, on the other hand, provides alternative examples of nanomedicinal applications in immunotherapy, noninvasive drug deliveries across epithelial barriers and strategies to combat intra- and extra-cellular bacterial infections. Looking ahead, access to highly complex nanoparticular delivery vehicles given nowadays may allow further improved therapeutic concepts against several diseases in the future too.

Abstract
This paper reports a new and general in situ methodology to grow fluorescent polymer conjugates from the interchain disulfide bridging sites of a monoclonal antibody. Atom transfer radical polymerization (ATRP) initiators were attached to a monoclonal antibody at its interchain disulfide bridging sites by disulfide re-bridging to yield a macroinitiator. Subsequent in situ ATRP of PEG-like monomers with dye-functionalized monomers from the macroinitiator formed antibody-polymer-dye conjugates with site-selectivity and tunable dye-to-antibody ratios. Notably, these conjugates can amplify antigen detection signal by reducing label-density dependent fluorescence quenching and by increasing dye-to-antibody ratios. The method developed may be applicable to a variety of antibodies, dyes and drugs to create a number of antibody-polymer-dye/drug conjugates for advanced diagnosis and therapy of diseases.
