Combining Clemastine and Aerobic Exercise to Treat Cognitive Dysfunction in Schizophrenia by Targeting Myelin Plasticity

Schizophrenia (SZ) is a broad clinical entity characterized by different subjective symptoms,behavioural signs, and disease course. Research has pointed to numerous biological indicators tentatively associated with neurocognitive dysfunction, brain structural and neurochemical alterations. Cognitive deficits occur as early as the prodromal phase of the illness and significantly determine its outcome. Pathophysiologically, SZ is regarded as a disconnectome disorder in which frontal and temporal brain regions are functionally disconnected, which contributes substantially to the development of cognitive dysfunction.
Impaired connectivity is related to synaptic (microconnectivity) and myelin (macroconnectivity) plasticity. With design-based stereology, a decreased number of oligodendrocytes (OLs) in the CA4 hippocampal subregion as the basis for disturbed myelination and impaired cognition, but also a decrease in the prefrontal cortex were observed. Animal studies demonstrated that clemastine enhances remyelination by increasing the differentiation of oligodendrocyte precursor cells (OPCs) and showed that aerobic exercise increases the rate of remyelination and proliferation of OPCs; this clinically meaningful effect of aerobic exercise is stronger in combination with clemastine. Furthermore, aerobic exercise improves everyday functioning, measured by the Global Assessment of Functioning (GAF) scale, and cognitive dysfunction in SZ and increases hippocampal volume, especially the volume in the hippocampal CA4 subregion. This regional volume change correlates negatively with global and cell-specific polygenic risk scores (PRSs), indicating that OPCs are involved in the genetic risk mechanisms and disturbed plasticity underlying SZ. In patients with multiple sclerosis, 90 days' administration of clemastine fumarate 10.72 mg/day, corresponding to clemastine 8 mg/day, significantly decreased the P100 latency delay of visual evoked potentials (VEPs) as a sign of myelin repair. In a bicentric, randomized, double-blind, controlled phase IIb clinical trial with a 2-arm parallel group design in patients with SZ, the study will compare the effects of aerobic exercise training plus clemastine vs. aerobic exercise training plus placebo over a period of 3 months on 1) everyday functioning and 2) working memory as primary outcomes.

Demyelination in the medial prefrontal cortex by withdrawal from chronic nicotine causes impaired cognitive memory

Article

作者: Huang, Bing ; Chen, Weiyuan ; Liu, Peipei ; Chen, Zifei ; Huang, Fang ; Gao, Fenfei ; Chen, Jieling ; Lu, Zhijie ; Wu, Jie

Epidemiological studies revealed deficits in cognitive learning and memory in smokers who withdrawal from smoking, but the molecular mechanisms underlying it is unclear. Here, we employed the novel object recognition task (NORT) to evaluate cognitive memory and found impaired memory and motor skills after withdrawal from chronic nicotine. Myelin sheath hastens the conduction of signals along axons and thus plays a critical role in learning and memory. We found no effect of nicotine withdrawal on the myelination in both of the Ventral tegmental area (VTA) and Nucleus accumbens (NAc) regions, but unexpectedly, we observed a demyelination phenomenon in the medial prefrontal cortex (mPFC) after withdrawal from chronic nicotine. Moreover, we found a positive correlation between the impaired memory and demyelination, and pharmaceutical rescue of myelination by clemastine specifically improved the impaired recognition memory but not the decreased motor skills caused by withdrawal from chronic nicotine. We further found nicotine directly acts on oligodendrocytes with OPCs potential to decrease their myelination process. Taken together, these results demonstrate demyelination in the mPFC causes impaired recognition memory and reveal a potential of enhancing myelination as a therapeutic strategy to alleviate cognitive memory deficits caused by smoking withdrawal.

The preferential effect of Clemastine on F3/Contactin-1/Notch-1 compared to Jagged-1/Notch-1 justifies its remyelinating effect in an experimental model of multiple sclerosis in rats

Article

作者: Kamel, Ahmed S ; Ahmed, Kawkab A ; Mohammed, Reham A ; Essam, Reham M ; Ibrahim, Sherehan M

Clemastine (CLM) is repurposed to enhance remyelination in multiple sclerosis (MS) patients. CLM blocks histamine and muscarinic receptors as negative regulators to oligodendrocyte differentiation. These receptors are linked to the canonical and non-canonical Notch-1 signaling via specific ligands; Jagged-1 and F3/Contactin-1, respectively. Yet, there are no previous studies showing the influence of CLM on Notch entities. Herein, the study aimed to investigate to which extent CLM aligns to one of the two Notch-1 arms in experimental autoimmune encephalomyelitis (EAE) rat model. Three groups were utilized where first group received vehicles. The second group was injected by spinal cord homogenate mixed with complete Freund's adjuvant on days 0 and 7. In the third group, CLM (5 mg/kg/day; p.o) was administered for 15 days starting from the day of the first immunization. CLM ameliorated EAE-associated motor and gripping impairment in rotarod, open-field, and grip strength arena beside sensory anomalies in hot plate, cold allodynia, and mechanical Randall-Selitto tests. Additionally, CLM alleviated depressive mood observed in tail suspension test. These findings harmonized with histopathological examinations of Luxol-fast blue stain together with enhanced immunostaining of myelin basic protein and oligodendrocyte lineage gene 2 in corpus callosum and spinal cord. Additionally, CLM enhanced oligodendrocyte myelination and maturation by increasing 2',3'-cyclic nucleotide 3'-phosphodiesterase, proteolipid protein, aspartoacylase as well. CLM restored the level of F3/Contactin-1 in the diseased rats over Jagged-1 level; the ligand of the canonical pathway. This was accompanied by elevated gene expression of Deltex-1 and reduced hairy and enhancer-of-split homologs 1 and 5. Additionally, CLM suppressed microglial and astrocyte activation via reducing the expression of ionized calcium-binding adaptor molecule-1 as well as glial fibrillary acidic protein, respectively. These results outlined the remyelinating beneficence of CLM which could be due to augmenting the non-canonical Notch-1 signaling over the canonical one.

Enhancing axonal myelination: Clemastine attenuates cognitive impairment in a rat model of diffuse traumatic brain injury

Article

作者: Feng, Yu ; Ma, Xiaohui ; Zong, Xuemei ; Huang, Zhihai ; Zhang, Quanguang ; Zhang, Yulan ; Jordan, J Dedrick

Traumatic brain injury (TBI) has a significant impact on cognitive function, affecting millions of people worldwide. Myelin loss is a prominent pathological feature of TBI, while well-functioning myelin is crucial for memory and cognition. Utilizing drug repurposing to identify effective drug candidates for TBI treatment has gained attention. Notably, recent research has highlighted the potential of clemastine, an FDA-approved allergy medication, as a promising pro-myelinating drug. Therefore, in this study, we aim to investigate whether clemastine can enhance myelination and alleviate cognitive impairment following mild TBI using a clinically relevant rat model of TBI. Mild diffuse TBI was induced using the Closed-Head Impact Model of Engineered Rotational Acceleration (CHIMERA). Animals were treated with either clemastine or an equivalent volume of the vehicle from day 1 to day 14 post-injury. Following treatment, memory-related behavioral tests were conducted, and myelin pathology in the cortex and hippocampus was assessed through immunofluorescence staining and ProteinSimple® capillary-based immunoassay. Our results showed that TBI leads to significant myelin loss, axonal damage, glial activation, and a decrease in mature oligodendrocytes in both the cortex and hippocampus. The TBI animals also exhibited notable deficits in memory-related tests. In contrast, animals treated with clemastine showed an increase in mature oligodendrocytes, enhanced myelination, and improved performance in the behavioral tests. These preliminary findings support the therapeutic value of clemastine in alleviating TBI-induced cognitive impairment, with substantial clinical translational potential. Our findings also underscore the potential of remyelinating therapies for TBI.

什么Biotech让强生和百济二股东看好？

昨日（4月1日），随着Contineum Therapeutics的FORM S-1文件更新披露，已经可以看到这家Biotech IPO过程的具体细节。此次IPO预计将会以16-18美元/每股发放880万股，最终募股规模有可能超过此前预计的1.5亿美元。股东方面，之前就是Contineum Therapeutics投资人的强生附属基金JJDC，知名资本Sectoral Asset Management，还吸引来了曾经的Seagen大股东和现在百济二股东Baker Brother。Contineum Therapeutics将是今年第八家申请上市的Biotech企业，但是与之前几家IPO的比如说：Alto Neuroscience、ArriVent Biopharma、CG Oncology、Kyverna Therapeutics和Metagenom较为不同的是，这家小分子药物公司的IPO募股金额相对较高，适应症上主要开发多发性硬化症（MS）这一红海市场，目前管线还都处于临床早期。按理来说，多发性硬化症是罕见病中竞争较为激烈的红海市场，从市场角度来看，曾经的霸主Biogen（渤健）这几年都因为仿制药和竞争对手罗氏的深度参与，销量大幅下滑了。竞争激烈程度可见一斑。而在这种情况下，这家公司能得到强生看重，肯定有其特殊的地方。管线概览虽然同样是MS，但是Contineum的管线机制与许多企业大相径庭。现有的MS治疗手段如富马酸二甲酯，Ocrelizumab等治疗手段都是通过抑制炎症的途径来进行治疗的。而Contineum Therapeutics已经明确适应症的管线采用的是两种与现有治疗药物机制完全不同的路线：一种是溶血磷脂酸1受体（LPA1R）抑制剂PIPE-791，另外一种是毒蕈碱1型M1受体（M1R）抑制剂PIPE-307。此外，这家公司还有一款不明适应症的管线：LPA1R抑制剂CTX-343。虽然这两款药物都有两种不同细分的MS适应症，但这家企业也没死磕MS，PIPE-791还能用于开发特发性肺纤维化（IPF），PIPE-307则被额外开发用于抑郁症。强生似乎很看重PIPE-307，Contineum Therapeutics（当时还叫Pipeline Therapeutics）在去年4月与强生授权交易中，不仅获得了5000万美元的预付款，有望获得10亿美元里程碑付款，还获得了2500万美元的股权投资和2500万美元的现有投资人投资。LPA1R抑制剂的开发溶血磷脂酸（LPA）是一种通过特异性G蛋白偶联受体（LPAR）发挥作用的生物活性介质，目前对其在纤维化病因中的作用有所了解。在许多器官中，纤维化与LPA产生增加以及某些LPAR亚型（主要是LPA1R）表达增加有关。所以PIPE-791的适应症是IPF似乎不难理解，而在MS中的应用主要起始于近几年Contineum Therapeutics的开发。MS是一种炎症性脱髓鞘疾病，导致神经元传递中断，最终导致神经变性。目前的治疗重点是抑制免疫系统，以限制炎症和髓鞘的进一步丧失。先前的几篇文献发现，在MS中，炎性脂质、溶血磷脂酸(LPA)水平升高，这种炎症脂质的升高对于MS病情进展是不利的。除了神经炎症，LPA还会抑制少突胶质前体细胞(OPC)分化。而少突胶质前体细胞是产生髓鞘化细胞的细胞，而MS常常伴随着慢性脱髓鞘，抑制LPA可能有助于MS中髓鞘化细胞的再生。而PIPE-791就是这一成果转化的产物。PIPE-791是首个口服生物可利用的脑渗透LPA1拮抗剂。毒蕈碱1型m1受体抑制剂大部分对毒蕈碱1型m1受体抑制剂的开发都集中在阿尔兹海默症和精神疾病如精神分裂症，但是Contineum Therapeutics竟然将其用于了MS上。机理机制和上述LPA用于MS的类似。以前MS的治疗药物主要通过抑制炎症途径来减少进展，而Contineum的注意力集中在调节髓鞘再生的分子上。MI毒蕈碱乙酰胆碱受体(MIR)已被证明是少突胶质前细胞(OPCs)成熟为少突胶质细胞(OLs)的关键调节剂，少突胶质细胞是制造髓磷脂的细胞。这一发现是基于非选择性抗毒蕈碱化合物，如Clemastine和Benzetropine，并随后通过细胞类型特异性MIR敲除研究验证。基于这一初步发现，Contineum就开始了一项药物化学研究，以发现一种新的MIR选择性拮抗剂。最初产生的拮抗剂是是PIPE-359，后续跟进迭代产生了PIPE-307。临床前研究表明，PIPE307可诱导功能性髓鞘再生。点评总的来看，PIPE307和PIPE-791在机制上其实和现有MS并不冲突，甚至能够互补，现有治疗手段大多着重于抑制炎症途径，而抑制炎症途径只能起到延缓作用，联合使用这两款药物可能改变现有MS的格局。这可能是强生对这家企业另眼先看的原因。不过也值得注意的是，虽然PPT讲得好是一回事，但是实际患者再生的有效性是另外一回事。PIPE307和PIPE-791是否能在疗效上展现出具有统计学意义上的临床改善或许才是关键。参考来源：Rancoule C, Pradère JP, Gonzalez J, Klein J, Valet P, Bascands JL, Schanstra JP, Saulnier-Blache JS.
