Allergic asthma can be precipitated by many factors. For the atopic person, fungus, pollen, dust mites, cockroach antigens, and diesel exhaust are all agents that may trigger an allergic attack. Cytokines and chemokines are integral mediators of fungal asthma. From the earliest time points, they recruit and activate the cells required for the clearance of fungus as well as being critical factors involved in the immunopathology of this disease. In the final analysis, it is clear that these mediators can act to the benefit or the detriment of the host.

CAFs-released exosomal CREB1 promotes cell progression and immune evasion in thyroid cancer via the positive regulation of CCL20.
Autoimmunity

Department of Thyroid Head and Neck Surgery, The Affiliated Cancer Hospital of Zhengzhou University, Henan Cancer Hospital, Zhengzhou, China.
Background: Exosomes derived from cancer-associated fibroblasts (CAFs) can affect tumor microenvironment (TME) of thyroid cancer (TC). The cAMP response element binding protein 1 (CREB1) acts as a transcription factor to participate in cancer development. Currently, we aimed to explore the molecular mechanism of exosome-associated CREB1 and C-C motif chemokine ligand 20 (CCL20) in TC.

To explore biomarkers for the efficacy of lymphocyte immunotherapy (LIT) treating women with unexplained recurrent spontaneous abortion (URSA). Serum samples from 24 URSA potients who received LIT were collected at Peking University Third Hospital from December 2014 to June 2015. Semiquantitative sandwich-based antibody arrays containing 40 cytokines were used to screen target immune cytokines in the peripheral blood of URSA patients before and after LIT.

Objectives: To evaluate the potential of clinical factors, ultrasound findings, serum autoantibodies, and serum cytokine and chemokine profiles as predictors of clinical outcomes in rheumatoid arthritis (RA).
Patients And Methods: We included 200 patients with RA treated with biological and targeted synthetic disease-modifying antirheumatic drugs in a prospective multicentre ultrasound cohort study. Their serum levels of multiple cytokines and chemokines, rheumatoid factors, and serum autoantibodies (anti-cyclic citrullinated peptide-2 (anti-CCP2) and anti-carbamylated protein antibodies) were measured at baseline, 3 months and 12 months.
Pericytes mediate neuroinflammation via Fli-1 in endotoxemia and sepsis in mice.

Department of Pathology and Laboratory Medicine, Medical University of South Carolina, 173 Ashley Ave, Charleston, SC, 29425, USA.
Background: Sepsis-associated encephalopathy (SAE) often results from neuroinflammation. Recent studies have shown that brain platelet-derived growth factor receptor β (PDGFRβ) cells, including pericytes, may act as early sensors of infection by secreting monocyte chemoattractant protein-1 (MCP-1), which transmits inflammatory signals to the central nervous system. The erythroblast transformation-specific (ETS) transcription factor Friend leukemia virus integration 1 (Fli-1) plays a critical role in inflammation by regulating the expression of key cytokines, including MCP-1.

Departamento de Morfologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte, 31270-901, Brazil.
Objective: We aimed to understand the potential therapeutic and anti-inflammatory effects of the phosphodiesterase-4 (PDE4) inhibitor roflumilast in models of pulmonary infection caused by betacoronaviruses.
Methods: Mice were infected intranasally with murine hepatitis virus (MHV-3) or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Roflumilast was given to MHV-3-infected mice therapeutically at doses of 1 mg/kg or 10 mg/kg, or prophylactically at 10 mg/kg.
