RNA, on the other hand, is readily taken up and expressed by DC, making it an alternative vaccine candidate.
FROM THE CLINICAL EDITOR The use of self-amplifying replicon RNA (RepRNA) to increase vaccine antigen payloads can potentially be useful in effective vaccine design.
Preclinical and clinical applications of self-amplifying RNA viral vectors have proven efficient for vaccine development and due to the presence of RNA replicons, amplification of RNA in host cells will generate superior immune responses with significantly reduced amounts of RNA delivered.
We therefore suggest that RNA-transfected DC vaccine efficacy could be improved by the use of mRNA targeted to the proteasome.
These results illustrate that for an RNA-based vector the RNA sequence of the antigen can have profound and unforeseen consequences on vaccine behaviour.
These preclinical studies demonstrate that an RNA tumor antigen vaccine strategy has potential application for human cancer treatment and prevention.
RNA are potential vaccine adjuvants for immune enhancement against cancer and provide a benefit for vaccinations.
The RNA initiates limited replication of a genetically defined, live-attenuated vaccine virus in the tissues of the vaccine recipient, thereby inducing a protective immune response.
This demonstrates that DNA vaccine potency may be augmented by the incorporation of RIG-I-activating immunostimulatory RNA into the vector backbone.

Fermented foods, rich in living microorganisms and bioactive compounds, have shown potential in alleviating allergic diseases. Lactic acid bacteria found in fermented dairy products play a crucial role in mitigating allergic diseases by targeting milk allergen epitopes. Additionally, high-fiber or high-fermented diets have been linked to a reduction in allergic outcomes by influencing the gut microbiota and immune responses. Experimental samples prepared under various fermentation conditions with medicinal plant extracts demonstrated anti-allergic efficacy, suggesting fermented products could effectively reduce allergy symptoms with fewer side effects. Furthermore, the fermented soy product ImmuBalance has been reported to inhibit airway inflammation in a murine model of asthma, indicating the potential of fermented foods in preventing or treating allergic airway inflammation. Fermented foods offer a promising strategy in modulating immune responses and reducing the risk of allergic diseases.
What is the structural difference between firmicutes and other bacterial domains?
5 answers
Firmicutes exhibit distinct genomic features compared to other bacterial domains. They often display Purine Asymmetry (PAS), Strand-biased Gene Distribution (SGD), and contain the PolC isoform of DNA polymerase III alpha subunit. Additionally, Firmicutes are characterized by a dominance of specific bacterial Classes, such as Bacillales, Lactobacillales, and Clostridiales, which are linked to their physiology as lactic acid bacteria. In contrast, Actinobacteria possess a unique family of proteins, like the resuscitation-promoting factor (Rpf), which controls growth and resuscitation through muralytic enzymes, a feature not exclusive to Firmicutes. These differences in genomic characteristics and protein families highlight the structural distinctions between Firmicutes and other bacterial domains.

Vitamin C plays a significant role in enhancing the immune system. Research indicates that vitamin C can boost immunity by influencing immune responses and gene expression. Specifically, in the context of COVID-19, vitamin C has been studied for its potential positive impact on the immune system. Studies have shown that vitamin C supplementation can elevate levels of key cytokines like interferon and interleukins, which are crucial for immune responses. Moreover, vitamin C has been linked to active DNA demethylation, promoting the differentiation and maturation of dendritic cells, essential for bridging innate and adaptive immune responses. Overall, the evidence suggests that vitamin C can indeed have a significant influence on the immune system, potentially improving immune responses and overall health.
How is inflammatory microglia in als?
4 answers
In amyotrophic lateral sclerosis (ALS), inflammatory microglia play a crucial role in neurodegeneration. These microglia are involved in various processes such as pyroptosis activation, release of pro-inflammatory factors, and dysregulation of microRNAs, contributing to motor neuron loss. Studies have identified distinct subgroups of microglia in ALS lesions, indicating different inflammatory responses. The activation of the NLRP3 inflammasome in microglia triggers pyroptosis, leading to neuronal degeneration. Additionally, the MAPK/MAK/MRK overlapping kinase (MOK) has been found to regulate inflammatory responses in microglia, impacting motor neuron survival. Understanding the complex role of inflammatory microglia in ALS pathogenesis is crucial for developing targeted therapeutic strategies to modulate neuroinflammation and potentially slow down disease progression.
Trisomy 21 and Periodontitis in patients who have had cancer treatment?
5 answers
Trisomy 21 patients with periodontitis have shown the presence of herpesviruses and periodontopathic bacteria in their oral microbiome. Additionally, cancer patients with periodontitis exhibit higher levels of IL-6 and T regulatory cells (Treg) in their peripheral blood, potentially contributing to immunosuppression and cancer progression. Furthermore, a study on the systemic impact of periodontitis revealed that proper treatment for periodontitis can reduce cancer risk, indicating that periodontitis is a modifiable risk factor for cancer. Moreover, a large-scale retrospective cohort study demonstrated a significant association between periodontitis and increased cancer risk, including stomach, colon, lung, bladder, thyroid, and leukemia cancers, even after adjusting for confounding factors. Therefore, Trisomy 21 patients who have undergone cancer treatment and have periodontitis may face a complex interplay of factors affecting their oral health and cancer risk.
Periodontitis in patients who have had cancer treatment?

Periodontitis in patients who have undergone cancer treatment can have significant implications. Research suggests that periodontitis may impact cancer occurrence and progression. Patients with both periodontitis and cancer show increased levels of T regulatory cells (Treg) and IL-6 in peripheral blood, potentially contributing to immunosuppression and cancer progression. Moreover, individuals with periodontitis have a higher overall cancer risk, including specific cancers like prostate, thyroid, stomach, colon, lung, bladder, thyroid, and leukemia. Proper treatment for periodontitis has been shown to reduce cancer risk, indicating that periodontitis is a modifiable risk factor for cancer. Dental care for cancer patients is crucial, as chemotherapy can exacerbate oral health issues, emphasizing the need for specialized dental treatment in this population.
What is TE exonization ?
5 answers
TE exonization refers to the process where transposable elements (TEs) inserted into intronic regions of genes provide splice sites, leading to the creation of alternatively spliced cassette exons. This event enriches transcriptomes and proteomes by generating diverse RNA transcripts and protein isoforms. TE exonization can contribute significantly to the complexity of transcriptomes, with up to 71% of exonized transcripts being potential targets for the nonsense-mediated decay pathway. The incorporation of TE-derived sequences into coding regions of genes can expand the proteome diversity by offering new protein isoforms. Additionally, TE exonization can be regulated by epigenetic mechanisms, such as histone modifications, to control the expression of TE-derived coding sequences in different cell types.
Whats the origin of the placebo effect?
5 answers
The origin of the placebo effect can be traced back to the late 1940s when placebos, understood as inert substances, were introduced as a crucial tool in clinical research. The term "placebo" originates from the Latin word "placere," meaning "I will delight" or "do good". Initially defined as a medicine given more to please than to benefit the patient, placebos were used to appease patients without affecting pathophysiology. Over time, the concept evolved to include the therapeutic potential of inert agents in controls, with subsequent research quantifying the magnitude of the placebo effect. The placebo effect is a complex phenomenon influenced by various factors such as patient expectations, psychological variables, and neurochemical responses, ultimately leading to subjective changes in pain perception and clinical outcomes.
Nigericin causes cells to undergo pyroptosis and this is characterised by?
5 answers
Nigericin induces pyroptosis in cells, characterized by the activation of Caspase-1/GSDMD-mediated pyroptosis and Caspase-3-mediated apoptosis, leading to cell death. This process involves mitochondrial dysfunction, mitochondrial ROS production, and cellular potassium efflux triggered by nigericin, resulting in the activation of T cells and amplification of the anti-tumor immune response. Additionally, nigericin-induced pyroptosis is associated with ribosome stalling, depletion of cytosolic potassium ions, and activation of the ribotoxic stress response (RSR) sensor kinase ZAKɑ, p38, and JNK. Furthermore, nigericin-induced pyroptosis in primary effusion lymphoma (PEL) cells involves mitochondrial dysfunction, caspase-9-mediated apoptosis, and down-regulation of Wnt/β-catenin signaling. Overall, nigericin-induced pyroptosis is a complex process involving multiple molecular pathways and cellular responses.
