Abstract:
... High-throughput single-cell analysis today is facilitated by protocols like the 10X Genomics platform or Drop-Seq which generate cDNA pools in which the origin of a transcript is encoded at its 5′ or 3′ end. Here, we used R2C2 to sequence and demultiplex 12 million full-length cDNA molecules generated by the 10X Genomics platform from ~3000 peripheral blood mononuclear cells. We use these reads, i ...

Abstract:
... The current study was designed to introduce an efficient epitope-based vaccine against bovine babesiosis. Four immunogenic proteins of the Babesia. bovis including Trap, msa, bov57 and 12D3 were selected from VIOLIN database, then the proteins were used for prediction of B cell and T cell epitopes. The predicted epitopes along with HBHA protein as a molecular adjuvant were used to design an epitop ...

Abstract:
... Aminoacyl-tRNA synthetases (ARSs) are emerging as important regulators in various immune diseases; however, their roles in immune cells remain unclear. In this study, using alanyl-tRNA synthetase (AARS) mutant (sti) mice with neurodegenerative disorder, we investigated the effect of translational fidelity in immune cells. Dysfunctional AARS caused disorders in immune cell responses and cellularity ...

Abstract:
... Chimeric antigen receptor (CAR) is a single-pass transmembrane receptor designed to specifically target and eliminate cancers. While CARs prove highly efficacious against B cell malignancies, the intracellular signaling events which promote CAR T cell activity remain elusive. To gain further insight into both CAR T cell signaling and the potential signaling response of cells targeted by CAR, we an ...

Abstract:
... The clinical manufacturing of chimeric antigen receptor (CAR) T cells includes cell selection, activation, gene transduction, and expansion. While the method of T-cell selection varies across companies, current methods do not actively eliminate the cancer cells in the patient’s apheresis product from the healthy immune cells. Alarmingly, it has been found that transduction of a single leukemic B c ...

... Bacillus cereus hemolysin II, a pore-forming β-barrel toxin (HlyII), has a C-terminal extension of 94 amino acid residues, designated as the C-terminal domain of HlyII (HlyIICTD). HlyIICTD is capable of forming oligomers in aqueous solutions. Oligomerization of HlyIICTD significantly increased in the presence of erythrocytes and liposomes. Its affinity for erythrocytes of various origins differed ...

Abstract:
... T cells genetically engineered to express chimeric antigen receptors (CAR) have shown unprecedented results in pivotal clinical trials for patients with B cell malignancies or multiple myeloma (MM). However, numerous obstacles limit the efficacy and prohibit the widespread use of CAR T cell therapies due to poor trafficking and infiltration into tumor sites as well as lack of persistence in vivo. ...
T-lymphocytes, etc ; histone deacetylase; leukemia; proteolysis; Show all 4 Subjects
Abstract:
... We developed a first-in-class proteolysis targeting chimera (PROTAC) for selective degradation of histone deacetylase 8 (HDAC8). The PROTAC induced degradation of HDAC8 without affecting the levels of other HDACs in cellular assays, and inhibited the growth of T-cell leukemia Jurkat cells more potently than a conventional HDAC8 inhibitor. ...

Abstract:
... The function and antigen-specificities of tumor-infiltrating B cells are mostly unknown. In a new study by Mazor et al., matrix metalloproteinase 14 (MMP14), a self-antigen that is overexpressed by ovarian cancers, is shown to drive B cell activation and autoantibody production in tertiary lymphoid structures (Mazor et al., 2022). ...

Abstract:
... Follicular regulatory T cells (Tfrs), a specialized subset of regulatory T cells (Tregs), have a particular role in the control of follicular helper T cell-driven germinal center (GC) responses. Following differentiation signals similar to those received by follicular helper T cells (Tfhs), Tfrs gain expression of characteristic chemokine receptors and transcription factors, such as CXCR5 and Bcl- ...

Abstract:
... Arboviral infections such as Chikungunya (CHIKV), Dengue (DENV) and Zika (ZIKV) are a major disease burden in tropical and sub-tropical countries, and there are no effective vaccinations or therapeutic drugs available at this time. Understanding the role of the T cell response is very important when designing effective vaccines. Currently, comprehensive identification of T cell epitopes during a D ...
... Our previous research revealed a novel function of berberine (BBR), a clinically relevant plant-derived alkaloid, as a suppressor of follicular T helper (Tfₕ) cell proliferation in secondary lymphoid organs of BBR-treated mice that underwent immunization for collagen-induced arthritis (CIA) in DBA1/J mice. Due to the importance of Tfₕ cell and B cell interactions in the generation of T cell-depend ...
... Background: T and B cell-mediated immunity can be assessed using T cell receptor excision circle (TREC) and Kappa-deleting recombination excision circle (KREC) analysis, respectively, and successful implementation of this method requires evaluation of the correlation between the TREC frequencies and T cell subsets as well as KREC levels and B lymphocyte subsets. The aim of the present study was to ...

Abstract:
... In a recent issue of Nature, Melenhorst et al. perform an extensive analysis of CAR T cells that persist for ten years in CLL patients. They find a dominant cytotoxic CD4+ population, raising the possibility that CD4+ T cells play an important role in durable CAR T cell therapy. ...

Abstract:
... Vaccines are the most cost-effective resource to contain and eliminate infectious diseases. Despite decades of research in the field, several pathogens have eluded the effect of conventional vaccines mostly due their failure in inducing strong T cell responses. There is a need for new vaccine technologies that can surpass this problem. Recent advances in imaging techniques have allowed the study o ...

Abstract:
... As robust dengue-specific CD4+ and CD8+ T cell responses are essential for protective immunity, we assessed cell-mediated immune (CMI) responses to a DENV-2-based dengue tetravalent vaccine candidate (TAK-003) in adolescents living in Panama, a dengue-endemic country. Peripheral blood mononuclear cells were collected from a subset of 67 participants ≥ 10 years old included in a phase 2 clinical tr ...
... Infants’ universal hepatitis A virus (HAV) single-dose vaccination has been highly effective for controlling HAV infection in Argentina, and in other Latin-American countries that adopted that strategy. Although antibodies wane over time, this has not been associated with HAV outbreaks or breakthrough infections, suggesting a relevant role for memory immunity. This study assessed long term humoral ...

Abstract:
... Activated CD8⁺ T lymphocytes differentiate into heterogeneous subsets. Using super-resolution imaging, we found that prior to the first division, dynein-dependent vesicular transport polarized active TORC1 toward the microtubule-organizing center (MTOC) at the proximal pole. This active TORC1 was physically associated with active eIF4F, required for the translation of c-myc mRNA. As a consequence, ...

Abstract:
... T lymphocytes are the major drivers of antitumor immunity. The recent clinical success of adoptive T cell therapies and immune checkpoint inhibitors has demonstrated the strength of modulating T cell function in fighting cancer. Nonetheless, a significant fraction of patients remain unresponsive largely due to the immunosuppressive tumor environment that blunts T cell activity. Small interfering R ...

Abstract:
... T-cell responses are fine-tuned by positive and negative co-signal molecules expressed on immune cells and adjacent tissues. VSIG4 is a newly identified member of the B7 family of ligands, which negatively regulates innate inflammatory and CD4⁺ T cell-mediated responses. However, little is known about the direct effects of VSIG4, which are exerted through an unidentified counter-receptor on CD8⁺ T ...
