Summary
Epstein-Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV) co-infection boosts KSHV persistence and cell transformation. This study introduces the first small animal model for primary effusion lymphoma (PEL), aiding future research.
Area of Science:
- Virology
- Oncology
- Immunology
Background:
- Kaposi's sarcoma human herpesvirus (KSHV) causes primary effusion lymphoma (PEL).
- Epstein-Barr virus (EBV) is frequently found alongside KSHV in PEL cases.
- Understanding the interplay between EBV and KSHV in PEL pathogenesis is crucial.
Purpose of the Study:
- To investigate the impact of EBV/KSHV co-infection on KSHV persistence and cell transformation.
- To develop and validate a novel small animal model for studying primary effusion lymphoma (PEL).
Main Methods:
- Development of a humanized mouse model for PEL research.
- Co-infection of the model with EBV and KSHV.
- Assessment of KSHV persistence and cellular transformation markers.
Main Results:
- EBV/KSHV co-infection significantly increases KSHV persistence in the humanized mouse model.
- Co-infection promotes KSHV-driven cell transformation.
- EBV replication stimulation is a key mechanism driving these effects.
Conclusions:
- The developed humanized mouse model is the first of its kind for studying PEL in small animals.
- EBV plays a critical role in enhancing KSHV persistence and oncogenic transformation in PEL.
- This model offers new avenues for therapeutic strategies against EBV/KSHV-associated lymphomas.

02:19Buffer Effectiveness
55.6K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

02:59Biological Effects of Radiation
18.1K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

01:20Infection
12.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:21Self-Awareness and Its Effects
318
Self-awareness is a psychological state in which the individual becomes the focal point of their attention. This inward focus transforms the self into an object of contemplation and assessment, influencing how individuals perceive their actions and their alignment with personal and societal standards.Triggers and Contexts for Self-AwarenessSelf-awareness can be activated by external stimuli that make individuals visually or audibly aware of themselves, such as mirrors, cameras, or recordings.

01:24Effects of feedback
1.1K
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...
