Special Issue Information

Dear Colleagues,

Adoptive cellular immunotherapies, particularly chimeric antigen receptor T-cells (CAR-T cells), have achieved great clinical success in the treatment of hematologic malignancies and show tremendous potential for cancer therapy. However, numerous caveats such as an immunosuppressive tumor microenvironment, impaired T cell metabolism and exhaustion, absence or loss of targets, and autologous CAR-T products with variable therapeutic efficacy currently limit effective and sustainable CAR-T cell therapy. Since CAR-redirected natural killer (NK) cells or NK-cells genetically engineered to express a functional T-cell receptor have demonstrated convincing therapeutic efficacy in preclinical and initial clinical studies, these cells represent promising alternative effectors for cellular immunotherapy. Similarly, numerous anti-tumor responses observed with genetically engineered invariant NKT cells suggest that redirected NKT cells may be of great therapeutic interest. Finally, improved bispecific T-cell or NK-cell engager formats are tested in clinical studies and are valuable candidates for complementing current immunotherapeutic strategies. Building on recent breakthrough findings and developments, this Special Issue will focus on advances to improve cellular immunotherapy of hematologic malignancies and invites researchers and experts in the field to contribute selected preclinical or clinical data on this exciting topic.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Lymphocyte collection by apheresis for CAR-T production usually does not include blood mobilized using granulocyte colony stimulating factor (G-CSF) due to the widespread knowledge that it causes a decrease in the number and functionality of lymphocytes. However, it is used for stem cell transplant, which is a common treatment for hematological malignancies. The growing demand for CAR therapies (CAR-T and NK-CAR), both in research and clinics, makes it necessary to evaluate whether mobilized PBSC products may be potential candidates for use in such therapies. This review collects recent works that experimentally verify the role and functionality of T and NK lymphocytes and the generation of CAR-T from apheresis after G-CSF mobilization. As discussed, T cells do not vary significantly in their phenotype, the ratio of CD4+ and CD8+ remains constant, and the different sub-populations remain stable. In addition, the expansion and proliferation rates are invariant regardless of mobilization with G-CSF as well as the secretion of proinflammatory cytokines and the cytotoxic ability. Therefore, cells mobilized before apheresis are postulated as a new alternative source of T cells for adoptive therapies that will serve to alleviate high demand, increase availability, and take advantage of the substantial number of existing cryopreserved products.
