Thus, the composition and the nature of the immune response is fundamentally different in the brain where avoiding immunopathology is prioritized compared to other peripheral organs. While the principle of immune privilege in the central nervous system (CNS) still holds true, the role of the immune system in the CNS has been revisited over the recent years. This redefining of immune privilege in the brain is a result of the recent re-discovery of the extensive CNS meningeal lymphatic system and the identification of resident T cells in the brain, meningeal layers, and its surrounding cerebrospinal fluid (CSF) in both humans and rodents. While neuro-immune interactions have been classically studied in the context of neuroinflammatory disease, recent works have also elucidated unconventional roles of immune-derived cytokines in neurological function, highlighting the many implications and potential of neuro-immune interactions. As a result, the study of neuro-immune interactions is becoming increasingly important in understanding both CNS homeostasis and disease.

The neuropathological hallmarks include the loss of dopaminergic neurons in the substantia nigra, the presence of Lewy bodies and Lewy neurites caused by α-synuclein aggregation, and neuroinflammation in the brain. The prodromal phase happens years before the onset of PD during which time many patients show gastro-intestinal symptoms. These symptoms are in support of Braak's theory and model where pathological α-synuclein propagates from the gut to the brain. Importantly, immune responses play a determinant role in the pathogenesis of Parkinson's disease. The innate immune responses triggered by microglia can cause neuronal death and disease progression. In addition, T cells infiltrate into the brains of PD patients and become involved in the adaptive immune responses. Interestingly, α-synuclein is associated with both innate and adaptive immune responses by directly interacting with microglia and T cells.

T helper cells are classically categorized into different subsets, but heterogeneity exists within these subsets. Untangling the more complex regulation of these subsets will clarify their functional roles in neuroinflammation. Here, we will discuss how differentiation, immune checkpoint pathways, transcriptional regulation and metabolic factors determine the function of CD4<sup>+</sup> T cell subsets in CNS autoimmunity. T cells rely on metabolic reprogramming for their activation and proliferation to meet bioenergetic demands. This includes changes in glycolysis, glutamine metabolism and polyamine metabolism.

A particular focus of this review will be on the Th17/Treg balance and intra-subset functional states that can either promote or dampen autoimmune responses in the CNS and thus affect disease outcome.

Several major challenges have limited the development of novel therapeutics, including the extensive heterogeneity of tumor cell states within each glioblastoma and the ability of glioma cells to diffusely infiltrate into neighboring healthy brain tissue, including the contralateral hemisphere. A T cell-mediated immune response could deal with these challenges based on the ability of polyclonal T cell populations to recognize diverse tumor antigens and perform surveillance throughout tissues. Here we will discuss the major pathways that inhibit T cell-mediated immunity against glioblastoma, with an emphasis on receptor-ligand systems by which glioma cells and recruited myeloid cells inhibit T cell function. A related challenge is that glioblastomas tend to be poorly infiltrated by T cells, which is not only caused by inhibitory molecular pathways but also currently utilized drugs, in particular high-dose corticosteroids that kill activated, proliferating T cells. We will discuss innovative approaches to induce glioblastoma-directed T cell responses, including neoantigen-based vaccines and sophisticated CAR T cell approaches that can target heterogeneous glioblastoma cell populations.
