Special Issue Information

Dear Colleagues,

We are inviting you all to contribute to this Special Issue.

This is a platform for you all to contribute which we hope would contribute to advance schizophrenia therapeutics.

Despite significant advances, clinical use and effectiveness of antipsychotic medications to treat schizophrenia for over 6 decades, their precise molecular mechanisms of action remain unclear.

This is a platform to present and to discuss the theme of “What Remains to be discovered in schizophrenia therapeutics”. Of course, advancing the understanding of molecular mechanisms of action of antipsychotics remain the key to develop novel psychotropic medications to treat schizophrenia.

Contributions to this special issue may include below themes and we are also happy for your ideas as well:

  • Currently what is known about the effectiveness of antipsychotic drugs and related mechanisms
  • Antipsychotic drug mechanisms of action modifying the disease outcomes
  • What remains to be discovered?
  • Descriptions and definitions of terminology:
  • Advancing and revising the “schizophrenia”; moving forward
  • “Antipsychotic”: what new terminology should be developed, what makes sense and most useful?
  • Animal models of antipsychotic drug effects, construct and predictive validity
  • Approaches to reduce preclinical to clinical translation failures in antipsychotic drug development
  • Antipsychotic medication discovery approaches for known and novel molecular drug targets
  • Lessons learned from antipsychotic drug development failures
  • Beyond neurotransmitter-receptor dyads: intracellular signaling as antipsychotic targets
  • Novel antipsychotic approaches: neural networks instead of neurotransmitters
  • Molecular targets for one drug polypharmacy or multiple drug polypharmacy known and emerging molecular targets for positive psychotic symptoms
  • Molecular targets for negative psychotic symptoms in schizophrenia
  • Molecular targets for cognitive dysfunction in schizophrenia
  • Molecular targets for improved reward system functioning in schizophrenia
  • Molecular underpinnings of treatment resistant schizophrenia
  • Molecular targets for disease modification in schizophrenia
  • Molecular targets for improved safety and tolerability of antipsychotic agents
  • Novel modes of delivery for antipsychotic medications (e.g., subcutaneous, transdermal, intranasal, viral vector-based, etc)
  • Hypothesis-free rapid screening of compounds based on animal proxy measures of specific receptor and neural circuitry target effects that are deliberately screened in or screened out
  • Tropism of Sars-CoV-2 virus and its potential uses in molecular biology

Background: Induced pluripotent stem cell (iPSC) based neuronal differentiation is valuable for studying neuropsychiatric disorders and pharmacological mechanisms at the cellular level. We aimed to examine the effects of typical and atypical antipsychotics on human iPSC-derived neural progenitor cells (NPCs). Methods: Proliferation and neurite outgrowth were measured by live cell imaging, and gene expression levels related to neuronal identity were analyzed by RT-QPCR and immunocytochemistry during differentiation into hippocampal dentate gyrus granule cells following treatment of low- and high-dose antipsychotics (haloperidol, olanzapine, and risperidone). Results: Antipsychotics did not modify the growth properties of NPCs after 3 days of treatment. However, the characteristics of neurite outgrowth changed significantly in response to haloperidol and olanzapine. After three weeks of differentiation, mRNA expression levels of the selected neuronal markers increased (except for MAP2), while antipsychotics caused only subtle changes. Additionally, we found no changes in MAP2 or GFAP protein expression levels as a result of antipsychotic treatment. Conclusions: Altogether, antipsychotic medications promoted neurogenesis in vitro by influencing neurite outgrowth rather than changing cell survival or gene expression. This study provides insights into the effects of antipsychotics on neuronal differentiation and highlights the importance of considering neurite outgrowth as a potential target of action.

Schizophrenia is a frequently debilitating and complex mental disorder affecting approximately 1% of the global population, characterized by symptoms such as hallucinations, delusions, disorganized thoughts and behaviors, cognitive dysfunction, and negative symptoms. Traditional treatment has centered on postsynaptic dopamine antagonists, commonly known as antipsychotic drugs, which aim to alleviate symptoms and improve functioning and the quality of life. Despite the availability of these medications, significant challenges remain in schizophrenia therapeutics, including incomplete symptom relief, treatment resistance, and medication side effects. This opinion article explores advancements in schizophrenia treatment, emphasizing molecular mechanisms, novel drug targets, and innovative delivery methods. One promising approach is novel strategies that target neural networks and circuits rather than single neurotransmitters, acknowledging the complexity of brain region interconnections involved in schizophrenia. Another promising approach is the development of biased agonists, which selectively activate specific signaling pathways downstream of receptors, offering potential for more precise pharmacological interventions with fewer side effects. The concept of molecular polypharmacy, where a single drug targets multiple molecular pathways, is exemplified by KarXT, a novel drug combining xanomeline and trospium to address both psychosis and cognitive dysfunction. This approach represents a comprehensive strategy for schizophrenia treatment, potentially improving outcomes for patients. In conclusion, advancing the molecular understanding of schizophrenia and exploring innovative therapeutic strategies hold promise for addressing the unmet needs in schizophrenia treatment, aiming for more effective and tailored interventions. Future research should focus on these novel approaches to achieve better clinical outcomes and improve the functional level and quality of life for individuals with schizophrenia. Full article
