Cancer immunotherapy has revolutionized cancer treatment by harnessing the immune system's potential to combat cancer. Among the various strategies in this field, the use of killed tumor cells (KC) induced by immunogenic cell death (ICD) inducers has gained attraction. This approach involves the treatment of cancer cells in vitro, followed by the subcutaneous injection of these killed cells into tumor-bearing mice.

Article Synopsis
  • Wnt signaling is linked to synaptic plasticity, but the exact mechanisms and components involved are not fully understood.
  • Researchers found that exposure to the Wnt-5a ligand changes the threshold for inducing synaptic plasticity, promoting long-term potentiation (LTP) while inhibiting long-term depression (LTD) in hippocampal CA3-CA1 synapses.
  • The study highlights that Wnt-5a signaling enhances synaptic efficacy by increasing excitatory postsynaptic potentials and involves complex interactions with JNK and NMDAR, which can be blocked by the antagonist sFRP-2.

Article Synopsis
  • - Wnt signaling is crucial for various cellular processes, and Xenopus laevis oocytes serve as an effective model to study these mechanisms, particularly for receptors like Frizzled 7 found in the CNS.
  • - Using two-electrode voltage clamp recordings, researchers discovered that Wnt-5a affects the oocyte's membrane currents, resulting in changes to calcium-dependent currents, membrane depolarization, and alterations in potential and outward potassium currents.
  • - Wnt-5a treatment improved oocyte viability and enhanced germinal vesicle breakdown compared to the control, indicating that Wnt-5a influences oocyte structure and signaling, contributing to a deeper understanding of the Wnt pathway's cellular effects.

T-cell malignancies, including T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL), present significant challenges to treatment due to their aggressive nature and chemoresistance. Chemotherapies remain a mainstay for their management, but the aggressiveness of these cancers and their associated toxicities pose limitations. Immunepotent CRP (ICRP), a bovine dialyzable leukocyte extract, has shown promise in inducing cytotoxicity against various cancer types, including hematological cancers.

Brain edema is a critical complication arising from stroke and traumatic brain injury (TBI) with an important impact on patient recovery and can lead to long-term consequences. Therapeutic options to reduce edema progression are limited with variable patient outcomes. Aquaporin 4 (AQP4) is a water channel that allows bidirectional water diffusion across the astrocyte membrane and participates in the distinct phases of cerebral edema.

Cancer immunotherapies include monoclonal antibodies, cytokines, oncolytic viruses, cellular therapies, and other biological and synthetic immunomodulators. These are traditionally studied for their effect on the immune system's role in eliminating cancer cells. However, some of these therapies have the unique ability to directly induce cytotoxicity in cancer cells by inducing immunogenic cell death (ICD).

Background: Laryngeal squamous cell carcinoma (LSCC) represents one of the principal tumors of the head and neck. Human papillomavirus (HPV) and Epstein-Barr virus (EBV) are considered risk factors for the development and the clinical prognosis of LSCC. High levels of p16 are suggested as a surrogate marker of HPV or EBV infection in some head and neck tumors but in LSCC is still controversial.
