Naked, non-infectious, self-replicating RNA may be an excellent candidate for the development of new cancer vaccines.
As new cancer antigens come to the forefront with novel RNA encapsulation and targeting techniques, RNA vaccines may prove to be a vital, safe and robust method to initiate patient-specific anti-tumor efficacy.
Also, unlike DNA‐based vaccines, there is little danger of incorporation of RNA sequences into the host genome.
We also identified altered expression of these lncRNAs in RNA-sequencing (RNA-seq) data from a cohort of children following immunization with intranasal live attenuated influenza vaccine, suggesting a common role across several diverse vaccines.
Therefore, RNA adjuvants have broad applicability and can be used with all conventional vaccines to improve vaccine efficacy qualitatively and quantitively.
From this we conclude that sa-RNA is a promising platform for vaccines against viral diseases.
Our findings imply that bioavailability of recombinant RNA vaccines in vivo highly depends on the density and the maturation stage of DCs at the administration site and are of importance for the design of RNA-based clinical immunotherapy protocols.
This suggests that protein-based vaccines formulated using RNA adjuvant function as live-attenuated vaccines.

It regulates lipid metabolism by influencing the accumulation of triglycerides, cholesterol, and non-esterified fatty acids in cells, along with impacting the fatty acid beta oxidation pathway. CD36 is involved in lipid efflux through lipid metabolism, endocytosis, and amino acid metabolism, with various factors like RXRA being part of the CD36 signaling network. Additionally, CD36's absence can lead to reduced heart FA uptake, altered tissue energy balance, and compromised stress response in the heart, indicating its significance in maintaining tissue homeostasis. Overall, CD36's multifunctional role in lipid metabolism highlights its importance in cellular fatty acid uptake, metabolism, and overall tissue health.
How do parasites and hosts interact in the development of feline cutaneous leishmaniasis?
5 answers
Parasites and hosts interact in the development of feline cutaneous leishmaniasis through a complex process involving Leishmania infection, immune responses, and clinical manifestations. Cats, alongside dogs, have been identified as competent hosts for Leishmania parasites, particularly Leishmania infantum, contributing to the epidemiology of the disease in endemic areas like Brazil. The severity of feline leishmaniasis (FeL) varies, with skin lesions being the most common clinical sign, often affecting the head region, and in some cases progressing to visceral involvement. The immune response of cats to Leishmania infection is not extensively studied, but efficient infection control is observed in most cases. Additionally, the rapid progression of FeL from subclinical to severe forms underscores the importance of surveillance, differential diagnosis, and clinical care for infected cats.
How can be CRISPR/Cas9 used for making resistant bacteria susceptible again?
5 answers
CRISPR/Cas9 technology can be utilized to render antibiotic-resistant bacteria susceptible again by targeting and eliminating antibiotic resistance genes or plasmids within the bacterial genome. This molecular tool enables precise gene editing through the cleavage of specific DNA sequences. By using the CRISPR-Cas system, the Cas9 nuclease is guided by a single guide RNA to recognize and cut the target resistance genes. This targeted cleavage results in the removal of the resistance gene, thereby sensitizing the bacteria to antibiotics once more. The delivery of CRISPR-Cas9 into bacteria can be facilitated through bacteriophages, which act as vehicles for introducing the gene-editing system into the bacterial cells. This approach offers a promising strategy to combat antibiotic resistance and restore the susceptibility of bacteria to antimicrobial agents.

How whales evoluted from terrestrials animals?
5 answers
Whales evolved from terrestrial animals through a macroevolutionary transition, adapting to aquatic environments over 50 million years ago. Molecular studies on cetaceans have revealed adaptations in their genomes, such as unique tonsils, limited MHC diversity, and similarities in immunoglobulins and T cell receptor genes to terrestrial relatives. The evolution of whales involved complex interactions with retroviruses, with endogenous retroviruses (ERVs) providing insights into their evolutionary history. ERV analyses suggest that cetacean ERVs originated both before and after the transition to aquatic life, indicating a mix of endogenization events from terrestrial and non-cetacean mammals. Despite dissenting views on whale evolution, scientific evidence supports the gradual transition from land-dwelling ancestors to the specialized oceanic creatures we see today.
