New cell sources for CAR-based immunotherapy.

Chimeric antigen receptor (CAR) T cell therapy, in which a patient's own T lymphocytes are engineered to recognize and kill cancer cells, has achieved striking success in some hematological malignancies in preclinical and clinical trials, resulting in six FDA-approved CAR-T products currently available in the market. Despite impressive clinical outcomes, concerns about treatment failure associated with low efficacy or high cytotoxicity of CAR-T cells remain. While the main focus has been on improving CAR-T cells, exploring alternative cellular sources for CAR generation has garnered growing interest.

CAR-T cell potency: from structural elements to vector backbone components.

Chimeric antigen receptor (CAR) T cell therapy, in which a patient's own T lymphocytes are engineered to recognize and kill cancer cells, has achieved remarkable success in some hematological malignancies in preclinical and clinical trials, resulting in six FDA-approved CAR-T products currently available in the market. Once equipped with a CAR construct, T cells act as living drugs and recognize and eliminate the target tumor cells in an MHC-independent manner. In this review, we first described all structural modular of CAR in detail, focusing on more recent findings.

Exosomal MicroRNAs as Biomarkers in Allergic Asthma.

Exosomes are extracellular vesicles that are involved in intracellular communication and different biological processes. Recently, the importance of microRNAs (miRNAs) in exosomes has been considered as biomarkers in asthma diagnosis. This study aimed to determine the expression of selective miRNAs from plasma-derived exosomes in moderate and severe asthmatic patients compared with healthy controls.

Clinical and Genetic Study of X-linked Agammaglobulinemia Patients (The Benefit of Early Diagnosis).

X-linked agammaglobulinemia (XLA) is a primary immunodeficiency caused by genetic defects in the Bruton tyrosine kinase (Btk) gene. XLA is characterized as an antibody deficiency by recurrent bacterial infections, the absence of peripheral B cells, and profound reductions in all immunoglobulin isotypes. This study aims to report the clinical and genetic features of five Iranian patients with XLA.

Clinical and Genetic Analysis of Nine Suspected Familial Haemophagocytic Lymphohistiocytosis Patients for MUNC13-4 Deficiency and Introducing Four Novel Mutations in UNC13D.

Familial haemophagocytic lymphohistiocytosis (FHL) is a rare disorder of immune dysregulation. FHL inherited in an autosomal recessive pattern is classified into five subtypes based on underlying genetic defects. Mutations in four genes including PRF1, UNC13D, STX11 and STXBP2 are responsible for FHL2 to FHL5 respectively.

Asthma phenotypes and T-bet protein expression in cells treated with Fluticasone Furoate/Vilanterol.

Asthma is a complex disease with diverse clinical manifestations ranging from mild to severe. Despite existing guidelines for asthma recognition and treatment, still a proportion of patients stay uncontrolled. Combinational therapy which comprises inhaled corticosteroids (ICS) and a long acting B2 adrenreceptor agonist (LABA) has been suggested to control asthma.

Correction to: Chemical composition of PM10 and its effect on in vitro hemolysis.

[This corrects the article DOI: 10.1007/s40201-018-00327-w.].

Chemical composition of PM and its effect on in vitro hemolysis of human red blood cells (RBCs): a comparison study during dust storm and inversion.

Purpose: This study aimed to investigate chemical composition of PM (particulate matter with aerodynamic diameter ≤ 10 μm) during dust storm and inversion in Tehran and hemolysis effects.

Methods: PM was sampled in Tehran, Iran, during dust storm and inversion conditions. Water soluble ions (F¯, Cl¯, NO¯, NO¯, SO¯, Na, K, NH , Ca, Mg) and elements (Al, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Se, Sn, Sr, V, Zn, Pt, Rh, Pd, As and Si) were analyzed by ion chromatograph (IC) and inductively coupled plasma optical emission spectrometer (ICP-OES), respectively.

Glucocorticoid Receptor Nuclear Translocation in CD4 T Cells from Severe and Moderate Asthmatic Patients Treated with Fluticasone/Vilanterol.

Different phenotypes of asthma from mild to severe are categorized based on diverse clinical features. A guideline for the recognition and treatment of asthma has been provided by Global Initiative for Asthma (GINA). To control symptoms and prevent asthma exacerbation in most patients combinational therapy with inhaled corticosteroids (ICS) and a long acting B2-adrenreceptor agonist (LABA) are recommended.
