AI Article Synopsis
- Researchers are exploring the use of tick microbiota to combat tick-borne diseases like human granulocytic anaplasmosis (HGA) by leveraging a method called Frankenbacteriosis. !* -
- Frankenbacteriosis involves genetically modifying symbiotic bacteria in ticks to mimic pathogens, creating competition that reduces the opportunity for infection. !* -
- The modified bacteria produce a surface protein, MSP4, which interacts with the tick’s infection receptors, potentially allowing for lab-grown, genetically modified ticks that lower the transmission of pathogens and reduce HGA disease risks in the field. !*
Article Abstract
Tick microbiota can be targeted for the control of tick-borne diseases such as human granulocytic anaplasmosis (HGA) caused by model pathogen, . Frankenbacteriosis is inspired by Frankenstein and defined here as paratransgenesis of tick symbiotic/commensal bacteria to mimic and compete with tick-borne pathogens. Interactions between and symbiotic identified by metaproteomics analysis in midgut showed competition between both bacteria. Consequently, was selected for frankenbacteriosis for the control of infection and transmission. The results showed that Franken producing major surface protein 4 (MSP4) mimic pathogen and reduce infection in ticks by competition and interaction with cell receptor components of infection. Franken -MSP4 transovarial and trans-stadial transmission suggests that tick larvae with genetically modified Franken -MSP4 could be produced in the laboratory and released in the field to compete and replace the wildtype populations with associated reduction in pathogen infection/transmission and HGA disease risks.

The first evidence that Orthopoxvirus induced the expansion and the recall of effector innate Vδ2T-cells was described in a macaque model. Although, an engagement of αβ T-cells specific response in patients infected with human monkeypox (Mpox) was demonstrated, little is known about the role of γδ T-cells during Mpox infection. IFN-γ-producing γδ T-cells in the resistance to poxviruses may a key role in inducing a protective type 1 memory immunity.

Background: Skin wounds are highly common in diabetic patients, and with increasing types of pathogenic bacteria and antibiotic resistance, wounds and infections in diabetic patients are difficult to treat and heal.
Aim: To explore the effects of betaine ointment (BO) in promoting the healing of skin wounds and reducing the inflammation and apoptosis of skin cells in microbially infected diabetic mice.
Methods: By detecting the minimum inhibitory concentrations (MICs) of betaine and plant monomer components such as psoralen, we prepared BO with betaine as the main ingredient, blended it with traditional Chinese medicines such as gromwell root and psoralen, and evaluated its antibacterial effects and safety and .
