Alterations of the IKZF1-IKZF2 tandem in immune cells of schizophrenia patients regulate associated phenotypes.

Schizophrenia is a complex multifactorial disorder and increasing evidence suggests the involvement of immune dysregulations in its pathogenesis. We observed that IKZF1 and IKZF2, classic immune-related transcription factors (TFs), were both downregulated in patients' peripheral blood mononuclear cells (PBMCs) but not in their brain. We generated a new mutant mouse model with a reduction in Ikzf1 and Ikzf2 to study the impact of those changes.

Belief Bias in Individual and Collective Reasoning.

In this paper, we investigate whether collaborative group performance is better than individual performance in solving a syllogism evaluation task. We hypothesise that collaborative group settings will outperform individual settings and that the belief bias effect will be mitigated in a group setting. Two empirical studies were conducted with Argentinian undergraduate students.

Intestinal permeability biomarkers in patients with schizophrenia: Additional support for the impact of lifestyle habits.

Background: Emerging evidence suggests a potential association between "leaky gut syndrome" and low-grade systemic inflammation in individuals with psychiatric disorders, such as schizophrenia. Gut dysbiosis could increase intestinal permeability, allowing the passage of toxins and bacteria into the systemic circulation, subsequently triggering immune-reactive responses. This study delves into understanding the relationship between plasma markers of intestinal permeability and symptom severity in schizophrenia.

Peripheral airways dysfunction measured by oscillometry differentiates asthma from inducible laryngeal obstruction.

Background: Inducible laryngeal obstruction (ILO, also called vocal cord dysfunction) can be difficult to distinguish clinically from asthma. Limited studies have explored the use of respiratory oscillometry to detect changes unique to ILO, but more study is needed to determine if routine oscillometry can differentiate these two clinical entities.

Objective: Determine if impedance variables measured on routine oscillometry over tidal breathing vary between individuals with asthma and ILO.
