The CC chemokine receptor 6 (CCR6) is a G protein-coupled receptor family member that is highly expressed in B lymphocytes, certain subsets of effector and memory T cells, and immature dendritic cells. CCR6 has only one chemokine ligand, CCL20. The CCL20-CCR6 axis has been recognized as a therapeutic target for autoimmune diseases and tumor. This study developed specific monoclonal antibodies (mAbs) against mouse CCR6 (mCCR6) using the peptide immunization method. The established anti-mCCR6 mAb, CMab-13 (rat IgG, kappa), reacted with mCCR6-overexpressed Chinese hamster ovary-K1 (CHO/mCCR6), and mCCR6-endogenously expressed P388 (mouse lymphoid neoplasma) and J774-1 (mouse macrophage-like) cells in flow cytometry. The dissociation constant () of CMab-13 for CHO/mCCR6 cells was determined to be 2.8 × 10 M, indicating that CMab-13 binds to mCCR6 with high affinity. In summary, CMab-13 is useful for detecting mCCR6-expressing cells through flow cytometry.

Background: Cancer immunotherapy using immune checkpoint blockade (ICB) has revolutionized cancer treatment. However, patients with multiple myeloma (MM) rarely respond to ICB. Accumulating evidence indicates that the complicated tumor microenvironment (TME) significantly impacts the efficacy of ICB therapy.

Fas-associated protein with Death Domain (FADD) is a crucial signaling component of apoptosis and a vital immunomodulator on inflammatory signaling pathways. However, information on FADD-mediated apoptosis and immune regulation is limited in teleost. We herein cloned a FADD homolog, AjFADD, from Japanese eel (Anguilla japonica).

Leptin, NK cells, and the weight of immunity: Insights into obesity.

Obesity is a chronic inflammatory disease that affects more than 1 billion people worldwide and is associated with various metabolic and physiological dysfunctions, directly impacting the dynamics of the immune response, partly due to elevated leptin levels. Leptin is an important peptide hormone that regulates neuroendocrine function and energy homeostasis, with its blood levels reflecting energy reserves, fat mass, or energy deprivation. This hormone also plays a fundamental role in regulating immune function, including the activity of NK cells, which are essential components in antiviral and antitumor activity.

Dual-Enzyme-Instructed Peptide Self-Assembly to Boost Immunogenic Cell Death by Coordinating Intracellular Calcium Overload and Chemotherapy.

ACS Nano

Zhejiang Key Laboratory of Intelligent Cancer Biomarker Discovery and Translation, The First Affiliated Hospital, Wenzhou Medical University, Wenzhou 325035, Zhejiang, P. R. China.

The concept of immunogenic cell death (ICD) induced by chemotherapy as a potential synergistic modality for cancer immunotherapy has been widely discussed. Unfortunately, most chemotherapeutic agents failed to dictate effective ICD responses due to their defects in inducing potent ICD signaling. Here, we report a dual-enzyme-instructed peptide self-assembly platform of (CPT-GFFpY-PLGVRK-Caps) that cooperatively utilizes camptothecin (CPT) and capsaicin (Caps) to promote ICD and engage systemic adaptive immunity for tumor rejection.
