Article Abstract
Neuroinflammation plays important roles in the pathogenesis and development of autism spectrum disorder (ASD). However, the mechanism by which peripheral organ inflammation affects neuroinflammation is still unclear. This study aimed to investigate that the interaction between the lungs and the brain as a potential mechanism underlying this effect. Ovalbumin (OVA) can induce neuroinflammation and cause neurotoxicity, leading to tissue damage or cognitive memory impairment. OVA - induced maternal immune activation (MIA) provides a stable animal model for studying ASD and other human neurodevelopmental disorders. Postnatal reinfection is an additional risk factor for ASD and may lead to pathological and physiological changes. Here we compared the expression of cytokines in the hippocampus and lung tissues of MIA offspring after the second acute immune stimulation at three times post birth, as well as the correlation between cytokines and autism-like phenotypes.Interestingly, our research findings suggest that maternal and postpartum OVA-induced immune activation and lung injury may produce an autistic phenotype, with potential mechanisms involving the lung- brain axis.

Key factors underpinning neuroimmune-metabolic-oxidative (NIMETOX) major depression in outpatients: paraoxonase 1 activity, reverse cholesterol transport, increased atherogenicity, protein oxidation, and differently expressed cytokine networks.

Background: Major depressive disorder (MDD) is associated with neuro-immune - metabolic - oxidative (NIMETOX) pathways.
Aims: To examine the connections among NIMETOX pathways in outpatient MDD (OMDD) with and without metabolic syndrome (MetS); and to determine the prevalence of NIMETOX aberrations in a cohort of OMDD patients.
Methods: We included 67 healthy controls and 66 OMDD patients and we assessed various NIMETOX pathways.
Circadian Rhythm Disruption and Sleep Disorders in Alzheimer's Disease: Mechanistic Insights and Therapeutic Potentials.

Alzheimer's Disease (AD) is the leading cause of dementia worldwide, with significant cognitive and behavioural impairments that devastate individuals and their families. Cohort-level findings, demonstrate the broader population-level implications of Sleep and Circadian Rhythm Disruption (SCRD) in AD and underscore the need for early interventions, emphasizing the importance of timely action. However, the mechanism remains unclear.

Background: Parasite antigens and plasma lipopolysaccharide (LPS) levels from luminal origin in visceral leishmaniasis (VL) patients are correlated with cellular activation and low CD4+T cell counts.
Objectives: Our aim was to verify whether Leishmania infantum infection damages the intestinal barrier and whether combination antimonial/antibiotic contributes to the reduction of LPS levels and immune activation.
Methods: Golden hamsters were grouped in: G1-uninfected; G2-infected with L.
Distinct Evolutionary Signatures of Human Parainfluenza Viruses 2 and 4 Reveal Host Antagonism Divergence and Phylogenetic Discordance.

Human parainfluenza virus 2 (HPIV-2) and human parainfluenza virus 4 (HPIV-4) are significant but underappreciated respiratory pathogens, particularly among high-risk populations including children, the elderly, and immunocompromised individuals. In this study, we sequenced 101 HPIV-2 and HPIV-4 genomes from respiratory samples collected in western Washington State and performed comprehensive evolutionary analyses using both new and publicly available sequences. Phylogenetic and phylodynamic analyses revealed that both HPIV-2 and HPIV-4 evolve at significantly faster rates compared to mumps virus, a reference human orthorubulavirus.

Ion channels are integral membrane proteins which facilitate rapid transport of small ions into and out of the cell and between organelles and cytosol. Cytolytic lymphocytes including natural killer (NK) cells principally kill virus-infected and cancer cells by releasing cytolytic granules within the immunological synapse, formed between target and effector cells. This process strongly depends on Ca2+ signaling, which in human NK cells is controlled by the phospholipase C (PLCγ)/inositol-1,4,5-triphospate receptor (IP3R)/calcium release-activated calcium channel (CRAC) axis.
