Milk-derived exosomes in the regulation of nutritional and immune functions.

Milk-derived exosomes (MDEs), being a component of milk, have the potential to support immune system maturation in offspring and enhance immune cell proliferation. Through the transport and transmission of essential signaling molecules, MDEs contribute to the regulation of intergenerational and intraspecies communication, thereby impacting nutrient uptake and metabolic functions. A comprehensive comprehension of MDE functionalities is imperative for enhancing the quality of the dairy industry.

A combined miRNA-piRNA signature in the serum and urine of rabbits infected with Toxoplasma gondii oocysts.

Background: Increasing evidence has shown that non-coding RNA (ncRNA) molecules play fundamental roles in cells, and many are stable in body fluids as circulating RNAs. Study on these ncRNAs will provide insights into toxoplasmosis pathophysiology and/or help reveal diagnostic biomarkers.

Methods: We performed a high-throughput RNA-Seq study to comprehensively profile the microRNAs (miRNAs) and PIWI-interacting RNAs (piRNAs) in rabbit serum and urine after infection with Toxoplasma gondii oocysts during the whole infection process.

Parabronema skrjabini (Nematoda: Habronematidae) infection and development in the intermediate host-Haematobia irritans (Linnaeus, 1758) in Inner Mongolia, China.

Parabronemosis is a disease that severely threatens camel health, causing huge economic losses to industries involved in camel husbandry. Previous studies have reported that horn flies (Haematobia irritans) act as intermediate hosts of Parabronema skrjabini; however, the infection and developmental processes of P. skrjabini in horn flies remain unclear.

Acetylome analysis of the feline small intestine following Toxoplasma gondii infection.

Toxoplasma gondii is a protozoan parasite capable of infecting a large number of warm-blooded animals and causes serious health complications in immunocompromised patients. T. gondii infection of the feline small intestine is critical for the completion of the life cycle and transmission of T.

iTRAQ-based Quantitative Proteomics Analysis Identifies Host Pathways Modulated during Infection in Swine.

is a leading cause of foodborne illness and consumption of undercooked pig meat is a major risk factor for acquiring toxoplasmosis, which causes a substantial burden on society. Here, we used isobaric tags for relative and absolute quantification (iTRAQ) labelling coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify cellular proteins and pathways altered during infection in pigs. We also used parallel reaction monitoring-based LC-MS/MS to verify the levels of protein expression of infected spleens and mesenteric lymph nodes (MLNs).

Global Transcriptome Profiling of Multiple Porcine Organs Reveals -Induced Transcriptional Landscapes.

We characterized the porcine tissue transcriptional landscapes that follow infection. RNAs were isolated from liver, spleen, cerebral cortex, lung, and mesenteric lymph nodes (MLNs) of -infected and uninfected (control) pigs at days 6 and 18 postinfection, and were analyzed using next-generation sequencing (RNA-seq). altered the expression of 178, 476, 199, 201, and 362 transcripts at 6 dpi and 217, 223, 347, 119, and 161 at 18 dpi in the infected brain, liver, lung, MLNs and spleen, respectively.

Toxoplasma gondii ROP17 inhibits the innate immune response of HEK293T cells to promote its survival.

Toxoplasma gondii secretes a group of rhoptry-secreted kinases (ROPs), which play significant roles in promoting intracellular infection. T. gondii rhoptry organelle protein 17 (ROP17) is one of these important effector proteins.
