Abstract
Dendritic cells are the only antigen-presenting cells capable of activating naive T cells in humans and mammals and are the most effective antigen-presenting cells. With deepening research, it has been found that dendritic cells have many subsets, and the surface receptors of each subset are different. Specific receptors targeting different subsets of DCs will cause different immune responses. At present, DC-targeted research plays an important role in the treatment and prevention of dozens of related diseases in the clinic. This article focuses on the current status of DC surface receptors and targeted applications.

PHOTODERMATOLOGY PHOTOIMMUNOLOGY & PHOTOMEDICINE 2021; 38:158-168. [PMID: 34543492 DOI: 10.1111/phpp.12732] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 09/08/2021] [Accepted: 09/15/2021] [Indexed: 01/10/2023]
Abstract
BACKGROUND/PURPOSE Accurate assessment of malignant T-cell clones in patients with leukemic cutaneous T-cell lymphoma (L-CTCL) is crucial for diagnosis, treatment, and monitoring disease. Although multiple approaches to quantitate malignant T-cell clones have been reported, a cost-effective assay with broad coverage is not available. We report a NanoString-nCounter-Technology-based direct TCR expression assay (DTEA) that was previously developed to quantify both TCR-Vα and TCR-Vβ usages after adoptive immunotherapy. This study was performed to test the effectiveness of DTEA in assessing malignant T-cell clones in L-CTCL patients. METHODS Total RNAs extracted from peripheral blood mononuclear cells of patients before starting extracorporeal photopheresis (ECP) (n = 15) and during therapy at 3 months and 6 months (n = 12) were used for DTEA, with customized probes for 45 TCR-Vα and 46 TCR-Vβ family members. RESULTS At baseline, DTEA detected TCR-Vβ clones in all 15 patients (100%) compared to flow cytometry that detected TCR-Vβ clones in 9 of 13 patients (69.2%). In addition to predominant TCR-Vβ clones, DTEA also detected additional TCR-Vβ clones in 8 of 15 patients (53.3%). Furthermore, DTEA simultaneously identified clonal TCR-Vα usages, which allowed us to pair TCR-Vα and TCRVβ usages by malignant T-cells and identify diversified clonotypes. Changes in the relative frequencies of clonal TCR-Vβ and TCRVα usages over therapy were consistent with patients' clinical responses. CONCLUSIONS Our results indicate that DTEA can effectively assess malignant T-cell clones by detecting clonal TCR-Vα and TCR-Vβ usages. By providing a global view of TCR repertoires, DTEA may also help us understand the origin(s) of malignant T-cells and pathogenesis of CTCL.

Abstract
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global pandemic. However, the mechanism of tissue tropism of SARS-CoV-2 remains unclear. Here, recombinant receptor-binding subdomain 1 of spike protein of SARS-CoV-2 (RBD-SD1) was used as a probe to investigate the potential tropism of SARS-CoV-2 in thirty-three types of normal human tissues. RBD-SD1 probe was observed to interact with cells in reported SARS-CoV-2 infected organs. Interestingly, the RBD-SD1 probe strongly interacted with bone marrow cells in an angiotensin-converting enzyme 2 (ACE2)-independent manner. In addition, SARS-CoV-2 induced the ACE2 mRNA expression in human primary bone marrow cells, suggesting human bone marrow cells may be sensitive to SARS-CoV-2 infection. Therefore, human bone marrow cells could be strongly infected by SARS-CoV-2, which may play an important role in the pathogenesis of COVID-19. These findings provide a deeper understanding of SARS-CoV-2 infection routes, thus contributing to the treatment of COVID-19.
