Paraneoplastic Cerebellar Degeneration
Paraneoplastic cerebellar degeneration (PCD) is a rare neurological disorder that is often associated with underlying malignancies. At our company, we are committed to advancing drug and therapy development services for PCD, aiming to provide effective therapies for this challenging condition.
Overview of Paraneoplastic Cerebellar Degeneration
Paraneoplastic cerebellar degeneration (PCD) is a paraneoplastic neurological syndrome characterized by the immune-mediated destruction of Purkinje cells in the cerebellum. PCD often occurs in the setting of an underlying malignancy, with the immune response directed against both the tumor and the nervous system. This condition leads to progressive cerebellar dysfunction, resulting in symptoms such as ataxia, dysarthria, and nystagmus. The exact mechanisms underlying the immune-mediated neuronal damage are still under investigation, but cytotoxic T cells are considered the main effectors responsible for the loss of Purkinje cells in PCD.

Therapy Discovery and Development for PCD
The therapeutic of PCD is currently empirical, primarily focusing on two main pillars: treating the underlying cancer and utilizing general immunosuppressive drugs. In some cases, corticosteroids have shown limited effectiveness in PCD therapeutics. However, for PCD associated with anti-Yo antibodies, corticosteroids have been found to be ineffective. Alternative therapies such as plasma exchange and rituximab have shown promise in providing some benefit for these cases. The efficacy of intravenous immunoglobulins (IVIG) remains controversial, with conflicting results from different studies. The following links showcase our company's diverse therapeutic development platform, which can provide you with targeted PCD therapeutic development solutions.
Our Services
Drawing upon our vast expertise, our esteemed organization provides a comprehensive and all-encompassing service for the development of therapies targeting paraneoplastic cerebellar degeneration (PCD). We pride ourselves on offering a streamlined and efficient approach that caters to your unique requirements.
To better understand the pathogenesis of PCD and evaluate potential therapeutic interventions, we develop and utilize animal models and in vitro models that closely mimic the disease. These models allow us to study the mechanisms of PCD and test the efficacy of novel therapies.
Immunization Animal Models
One of the key strategies we employ is active immunization with recombinant Yo protein. By immunizing these mice with Yo protein, we aim to induce the production of anti-Yo antibodies and trigger an immune response similar to that observed in PCD cases.
We utilize cell lines derived from cerebellar tissue or neuronal progenitor cells, which are then exposed to the appropriate stimuli to induce immune responses and neuronal damage. These cell lines provide a valuable tool for studying the molecular and cellular mechanisms involved in PCD.
Our company specializes in the development of cerebellar organoids, which recapitulate the cellular diversity and architecture of the cerebellum. These organoids provide an excellent platform for investigating the interactions between immune cells, neurons, and other supporting cells in PCD.
Our preclinical research services involve conducting rigorous testing and evaluation of potential therapeutic candidates for PCD. In addition to the extensive array of services and models mentioned earlier, our proficiency extends to tailoring personalized solutions and creating disease models that precisely cater to your specific requirements. We take pride in our ability to adapt and customize our offerings to meet your unique needs. If our comprehensive range of services has captured your attention, we sincerely welcome you to reach out to us without any hesitation.
