Metabolism And B Cell Function

Received: 26 May 2021 / Revised: 16 June 2021 / Accepted: 23 June 2021 / Published: 26 June 2021

In recent years, the role of B cells in neurological disorders has significantly expanded our perspective on the mechanisms of neuroinflammation. The success of B-cell-depleting therapies in patients with CNS diseases such as neuromyelitis optica and multiple sclerosis has highlighted the importance of the neuroimmune cascade in the inflammatory process. While B cells are essential for the immune system and antibody production, they are also important contributors to pro- and anti-inflammatory cytokine responses in many inflammatory diseases. B cells can contribute to neurological diseases through peripheral immune mechanisms, including the production of cytokines and antibodies, or through CNS mechanisms. Emerging evidence suggests that abnormal pro- or anti-inflammatory B cell populations participate in neurological processes, including glial activation, which has been implicated in the pathogenesis of many neurodegenerative diseases. In this review, we summarize recent findings on B cell involvement in neuroinflammatory diseases and discuss the evidence to support the pathological immunomodulatory functions of B cells in neurological disorders, highlighting the importance of B cell-directed therapies. .

The central nervous system (CNS) was traditionally considered a site of severe immune privilege, because the brain parenchyma lacked lymphatic vessels and professional antigen-presenting cells, as well as physical barriers to circulating immune cells entering the brain. They were preventing it from happening. CNS. Later studies redefined the concept of immune privilege within the CNS as knowledge of the peripheral immune system and CNS interactions increased. Although the CNS is considered to be immune privileged, it is now clear that a small number of lymphocytes enter the lymphatic vessels of the CNS under healthy steady-state conditions and support immune surveillance of the CNS [ 1 ]. One channel of cellular dissemination through the CNS is through the cerebrospinal fluid (CSF). The choroid plexus is the main source of CSF and contains epithelial cells that form a tight barrier separating the blood and CNS [ 2 , 3 ]. CSF-Interstitial fluid (ISF) drainage follows specific pathways in the CNS, including the ventricles, subarachnoid space, parenchyma, and subcortical regions, and drains into deep cervical lymph nodes [ 4 , 5 ]. This functional connection between the CNS and cervical lymph nodes has further supported the concept of neuroimmune crosstalk [6, 7, 8, 9]. In an injured or inflamed CNS, lymphocytes, including T and B cells, multiply and can be found throughout the parenchyma, CSF-ISF, and perivascular and meningeal spaces because antigens are secreted to lymph nodes or the blood brain. Obstacles in the barrier. [3, 8, 10]. The emerging role of the adaptive immune system in the pathophysiology of neurological disorders has led to the successful development of therapies that specifically target the adaptive immune system, including B cell-depleting monoclonal antibodies.

Of the lymphocytes present in the CSF of a healthy individual, the vast majority are CD3 + T cells involved in immune surveillance, and B cells account for less than 1% [ 10 , 11 ], leading researchers to the majority of their efforts. focus on On the role of T cells and T cell subtypes in CNS immune regulation and autoimmunity. This focus has changed over the past few years, and the concept of B cells as regulators of CNS inflammation has emerged, leading to B cell-targeted therapies for various CNS and peripheral nervous system (PNS) diseases. development of The mechanism of B cell function in pathology can be complex. They play several critical roles in the immune system, including antigen presentation, cytokine production, and antibody secretion, so their contribution to the immune response in the CNS can be highly diverse.

In this review, we summarize the immunological properties of B cells and the CNS and discuss evidence that supports the emerging concept that B cells play an important role in regulating the innate and innate immune responses in various neurological disorders. do B cells are known to play a role in certain neuroinflammatory conditions, including neuromyelitis optica and autoimmune encephalitis where antibodies produced by B cells target CNS antigens, contributing to the injury [ 12 , 13 , 14 ]. Emerging evidence suggests that a range of neurodegenerative diseases also result from immune cell activation, and in this review, we focus on B cell-driven neuroinflammatory responses in diseases that have recently provided insight into our understanding. How the Immune System Contributes to the Pathogenesis of Neurology disorders, including multiple sclerosis (MS), Parkinson’s disease (PD), and Alzheimer’s disease (AD).

Together, B cells and T cells make up the adaptive immune system, and their primary role is to protect the body from harmful pathogens. Foreign substances that enter the body are recognized as antigens and trigger an immune response in which B and T cells in combination with other cell types are selectively recognized and eliminated by the immune system. While the B cell lineage is best known for its role in antibody generation and secretion, B cells participate in many aspects of the innate immune response, including antibody-dependent and -independent functions [15, 16, 17].

B cells develop in the fetal liver and postnatal bone marrow, where they undergo several well-defined maturation and differentiation stages in response to innate signals [ 17 ]. B cells mature from hematopoietic stem cells, which produce progenitor B cells, precursor B cells, immature, immature, transitional, and then mature B cells. In the presence of a specific antigen and with the help of T follicular helper cells, mature B cells that now reside in secondary lymphoid organs are activated and differentiate into antibody-producing plasma cells and memory B cells [18] . In general, surface expression of B220 and CD19 can identify cells committed to the B cell lineage and are often used for histological confirmation of B cell presence in both murine and human tissues. Another common B cell surface marker, CD20, is also expressed on mature B cells but is significantly reduced on plasma cells [ 19 , 20 ]. These cell surface proteins are common targets in B cell-directed therapies, such as rituximab and ocrelizumab, and ofatumumab, which target CD20-expressing B cells while sparing most antibody-producing plasma cells [21, 22]. In addition to antibody production, mature B cells function as uniquely specialized antigen-presenting cells (APC). B cells have specialized antigen processing machinery due to B cell receptor (BCR) signaling and HLA-DO expression. These properties allow BCR antigen presentation to be significantly more efficient and specific (up to 10,000-fold) than other APCs [ 23 ]. This highly efficient antigen presentation capability has been exploited for the development of B cell immunotherapy [24, 25, 26].

An important B cell effector mechanism is the selective release of a spectrum of cytokines. Naïve B cells do not secrete a wide range of cytokines after activation and require additional inducers from the immune microenvironment to increase their cytokine production. Outcomes of B cell signaling such as the induction of Th1/Th2 cells depend in part on environmental cues. For example, B cell receptor signaling induces B cell proliferation and production of pro-inflammatory cytokines, such as TNFα and IL-6 [ 27 , 28 , 29 ]. Although cytokine production is relatively widespread, their selective secretion from B cells is important for many aspects of immune health. For example, naive B cells produce cytokines that bind to CD4+ T cells and influence their subsequent function. Bacterial and viral infections can stimulate B cell production of tumor necrosis factor (TNF) and interferon gamma (IFNγ) which subsequently drive the differentiation of T cells to the Th1 pathway, resulting in macrophage activation and proliferation.
