IL-13 is a cytokine known to play a role in several pulmonary diseases, including asthma and fibrosis. The role of IL-13 in the context of pulmonary changes induced by helminth infection is unclear. Rats experimentally infected with Strongyloides venezuelensis and treated with anti-IL-13 neutralizing antibody were used to evaluate the role of IL-13 on functional and inflammatory changes of host lungs, and on parasite control. S. venezuelensis-induced airway hyperreactivity was IL-13-independent, but IL-13 played an essential role in driving airway mucus production and eosinophil infiltration. IL-13 was important for the control of egg production but not establishment in the intestine.

BLOC1S1 Control of Vacuolar Organelle Fidelity Modulates Murine T2 Cell Immunity and Allergy Susceptibility.

Background: The levels of biogenesis of lysosome organelles complex 1 subunit 1 (BLOC1S1) control mitochondrial and endolysosome organelle homeostasis and function. Reduced fidelity of these vacuolar organelles is increasingly being recognized as important in instigating cell-autonomous immune cell activation. We reasoned that exploring the role of BLOC1S1 in CD4 T cells may further advance our understanding of regulatory events linked to mitochondrial and/or endolysosomal function in adaptive immunity.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by persistent respiratory symptoms and airflow limitation. Interleukin-13 (IL13), associated with T-helper type 2 cells, plays a crucial role in COPD pathophysiology. This study aimed to investigate the relationship of single nucleotide polymorphisms (SNPs) in IL13 to COPD risk.

Alterations in the lipid layer and intercellular corneocyte connections can lead to increased allergen penetration through the skin surface. A normal cutaneous microbiome keeps the opportunistic pathogen Staphylococcus pseudintermedius levels low, but allergic inflammation leads to decreased diversity and increase in S pseudintermedius. Keratinocytes sound the initial allergen alarm via cytokine signaling and promote T-helper 2 (Th-2) inflammation.

Residual HCV-RNA and Elevated Platelet-to-Lymphocyte Ratio Predict Poor Long-Term Outcomes in Patients with Chronic Hepatitis C After Treatment.

Introduction: Despite achieving sustained viral response (SVR) after treatment with direct-acting antivirals (DAAs), the risk of liver disease progression and extrahepatic complications in chronic hepatitis C (CHC) remains. We aimed to determine the role of residual HCV-RNA in peripheral blood mononuclear cells (PBMCs), a condition known as occult hepatitis C (OCI), and systemic inflammatory markers as predictors of long-term outcomes in patients treated with DAAs.

Methods: We followed 42 patients treated with DAAs with OCI status determined after therapy, for a median of 6.
