As a novel toll-like receptor 9 (TLR9) agonist, synthetic unmethylated cytosine-phosphate-guanine (CpG) oligodeoxynucleotides can stimulate a Th1 immune response and potentially be used as therapeutic agents or vaccine adjuvants for the treatment of cancer. However, some drawbacks of CpG limit their applications, such as rapid elimination by nuclease-mediated degradation and poor cellular uptake. Therefore, repeat high-dose drug administration is required for treatment. In this work, a CpG delivery system based on 3-aminopropyltriethoxysilane (APTES)-modified Fe3 O4 nanoparticles (FeNPs) was designed and studied for the first time to achieve better bioactivity of CpG...

Undifferentiated Nasopharyngeal carcinoma (NPC) is ubiquitously identified with the Epstein-Barr virus (EBV), making this cancer a suitable candidate for cellular-based immunotherapy (CBI) due to its expression of potentially targetable tumor-associated viral antigens. Various preclinical and clinical studies have explored the use of cytotoxic T cells (CTLs), tumor-infiltrating lymphocytes (TILs), natural killer (NK) cells, and dendritic cells (DCs) in the treatment of both refractory and locally advanced NPC with some success...

AIM: DNA vaccines have emerged as a promising strategy for cancer immunotherapy; however, their immunogenicity is weak. Fms-like tyrosine kinase 3-ligand (Flt3L) has been exploited for its ability to increase the proliferation of dendritic cells (DCs). The aim of the present study was to investigate whether co-administration of an adjuvant plasmid expressing mouse Flt3L and a DNA vaccine of the Mucin 1 (MUC1) antigen enhances immune responses. METHODS: The recombinant plasmids pVAX1-MUC1 and pVAX1-Flt3L were constructed and injected into mice intramuscularly (i...

Regulatory T-cells (Treg) are critical for maintaining immune homeostasis. However, current Treg immunotherapies do not optimally treat inflammatory diseases in patients. Understanding the cellular processes that control Treg function may allow for the augmentation of therapeutic efficacy. In contrast to activated conventional T-cells, where protein kinase C-θ (PKC-θ) localizes to the contact-point between T-cells and antigen-presenting cells, in human and mouse Treg, PKC-θ localizes to the opposite end of the cell in the distal pole complex (DPC)...

Immunotherapy has exhibited enormous practice in the treatment of melanoma because of the intrinsic properties of tumor. Tumor can downmodulate immune function via multiple mechanisms such as immune checkpoint pathways. The PD-L1 monoclonal antibodies that block the PD1/PD-L1 pathway, which induced tumor cells to evade an immune attack, can delay tumor growth efficiently with inevitable disadvantages such as low selectivity and systemic toxicity. Nanomedicine is clearly an approach that holds tremendous potential for addressing the shortcomings and assisting delivery of drugs with proper biodistribution...

In 2017, an autologous chimeric antigen receptor (CAR) T cell therapy indicated for children and young adults with relapsed and/or refractory CD19+ acute lymphoblastic leukaemia became the first gene therapy to be approved in the USA. This innovative form of cellular immunotherapy has been associated with remarkable response rates but is also associated with unique and often severe toxicities, which can lead to rapid cardiorespiratory and/or neurological deterioration. Multidisciplinary medical vigilance and the requisite health-care infrastructure are imperative to ensuring optimal patient outcomes, especially as these therapies transition from research protocols to standard care...

BACKGROUND: Dendritic cells (DCs) are unique antigen presenting cells (APC) which play a pivotal role in immunotherapy and induction of an effective immune response against tumors. In the present study, 80% ethanol extract of Phyllanthus amarus was used to generate tumor lysate (TLY) derived from HCT 116 and MCF-7 cancer cell lines via induction of apoptosis. Monocyte-derived DCs were generated ex vivo from the adherent population of peripheral blood mononuclear cells (PBMCs). The generated TLY were used to impulse DCs to investigate its effect on their cellular immune functions including antigen presentation capacity, phagocytic activity, chemotaxis capacity, T-cell proliferation and cytokines release...

Cellular therapy is a key tool to treat haematological malignancies. Over 40,000 allogeneic and autologous haematopoietic stem cell transplants (HSCTs) are performed annually across Europe.1 Since 2017, a new T cell therapy, chimeric antigen receptor-T (CAR-T) cells have been licensed outside clinical trials. CAR-T cells have extremely potent antitumour activity, but also have a profile of toxic side effects not seen before. Cytokine release syndrome (CRS) and CAR-T cell-related encephalopathy syndrome (CRES) are common, predictable and potentially lethal side effects...

Allergic diseases, such as respiratory, cutaneous, and food allergy, have dramatically increased in prevalence over the last few decades. Recent research points to a central role of the microbiome, which is highly influenced by multiple environmental and dietary factors. It is well established that the microbiome can modulate the immune response, from cellular development to organ and tissue formation exerting its effects through multiple interactions with both the innate and acquired branches of the immune system...

Immunotherapy for Alzheimer's disease (AD) remains promising in the improvement of cognition and memory via the clearing of amyloid-β protein (Aβ) in the AD brain, despite some side effects. Our previous studies demonstrated that the 31-35 sequence of the Aβ molecule was the shortest active center and that polyclonal anti-Aβ31-35 antibody reduced neuronal apoptosis and cognitive impairments induced with acute Aβ application. The present study designed a novel single-chain variable fragment (scFv) monoclonal anti-Aβ31-35 antibody (scFv17) that specifically recognized extracellular Aβ and observed protective effects of scFv17 on pathological impairments in APP/PS1 transgenic mice...

Mechanistic details for the roles of sphingolipids and their downstream targets in the regulation of tumor growth, response to chemo/radiotherapy, and metastasis have been investigated in recent studies using innovative molecular, genetic and pharmacologic tools in various cancer models. Induction of ceramide generation in response to cellular stress by chemotherapy, radiation, or exogenous ceramide analog drugs mediates cell death via apoptosis, necroptosis, or mitophagy. In this chapter, distinct functions and mechanisms of action of endogenous ceramides with different fatty acyl chain lengths in the regulation of cancer cell death versus survival will be discussed...

Cancer immunotherapy aims to promote the activity of cytotoxic T lymphocytes (CTLs) within a tumour, assist the priming of tumour-specific CTLs in lymphoid organs and establish efficient and durable antitumour immunity. During priming, help signals are relayed from CD4+ T cells to CD8+ T cells by specific dendritic cells to optimize the magnitude and quality of the CTL response. In this Review, we highlight the cellular dynamics and membrane receptors that mediate CD4+ T cell help and the molecular mechanisms of the enhanced antitumour activity of CTLs...

Cholangiocarcinoma (CCA) is a cancer of the bile ducts that is associated with poor prognosis and poor treatment outcome. Approximately one-third of CCA patients can undergo surgery, but the recurrence rate is high and chemotherapy often cannot satisfactorily prolong survival. Cellular immunotherapy based on adoptive T-cell transfer is a potential treatment for CCA; however, the development of this technology and the search for an appropriate tumor-associated antigen are still ongoing. To enhance the cytotoxic activity of effector T cells against CCA, we developed self-differentiated monocyte-derived dendritic cells (SD-DC) presenting cAMP-dependent protein kinase type I-alpha regulatory subunit (PRKAR1A), which is an overexpressed protein that plays a role in the regulation of tumor growth to activate T cells for CCA cell killing...
