Special Issue Information

Dear Colleagues,

The genetic mechanism of somatic recombination occurs during B cell and T cell maturation and results in the diversity of antibodies and T cell receptors, allowing for broad recognition of antigens from nearly all pathogens. This ground-breaking discovery was awarded the Nobel Prize in Physiology or Medicine in 1987 (Tonegawa). Propelled along by these and other seminal findings (e.g., Chemical structure of antibodies by Edelman and Porter, 1972; Hybridoma techniques for monoclonal antibodies by Kohler and Milstein, 1984; Phage display for antibodies by Winter and Smith, 2018), recombinant antibodies have become a major class of biologics for disease treatments and have a therapeutic impact on cancers, autoimmune and inflammatory diseases, as well as infectious diseases.

The current Special Issue of Cells aims to collect papers with a focus on antibody production for drug discovery and development.  We welcome submissions on antibody production with original research and review articles exploring, but not limited to, the following specific sub-topics: Display technologies for antibody generation (phage, yeast, mRNA…);  hybridoma and single-cell technologies for antibody generation and discovery; computational and rational antibody engineering; transient expression technologies for antibody production; stable cell line development for antibody production; bioprocessing for antibody production; antibody purification; molecular assessment for antibody production; antibody epitope binning and binding affinity determination; analytical studies for antibody production; pharmacodynamic and pharmacokinetic studies for antibodies; in vitro and in vivo efficacy studies for antibodies; and toxicology studies for antibodies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract
Glypican-3 (GPC3) is an oncofetal antigen that is highly expressed in multiple solid tumors, including hepatocellular carcinoma, and is barely expressed in adult normal tissues except the placenta.

Glypican-3 (GPC3) is an oncofetal antigen that is highly expressed in multiple solid tumors, including hepatocellular carcinoma, and is barely expressed in adult normal tissues except the placenta. NKp46 activation receptor is expressed in all-natural killer (NK) cells, including tumor-infiltrating NK cells. FLEX-NKTM is a platform for the production of tetravalent multifunctional antibody NK cell engagers (NKE). CYT-303 was designed using the FLEX-NK scaffold, incorporating a novel humanized NKp46 binder that does not induce NKp46 internalization and a humanized GPC3 binder that targets the membrane-proximal lobe to mediate NK cell-redirected killing of HCC tumors. CYT-303 shows sub-nanomolar binding affinities to both GPC3 and NKp46. CYT-303 was highly potent and effective in mediating NK cell-redirected cytotoxicity against multiple HCC tumor cell lines and tumor spheroids. More interestingly, it can reverse the dysfunction induced in NK cells following repeated rounds of serial killing of tumors. It also mediated antibody-dependent cellular phagocytosis (ADCP) and complement-dependent cytotoxicity against GPC3-expressing HCC tumors. In vivo, CYT-303 showed no toxicity or cytokine release in cynomolgus monkeys up to the highest dose (60 mg/kg), administered weekly by intravenous infusion for 28 days. These results demonstrate the potential of CYT-303 to be a safe and effective therapy against HCC. Full article
