Nature Metabolism:湘雅二医院李霞/赵斌团队揭示1型糖尿病发展新机制,并提出治疗方法
生物世界· 2026-01-23 09:00
1 型糖尿病 (T1D) ,是一种慢性自身免疫疾病,其病因是免疫系统错误地攻击胰腺中产生胰岛素的 β 细胞 ,导致身体无法产生足够的胰岛素,进而导致血糖 水平升高。对于该疾病,目前尚无治愈方法,患者需要 终身依赖外源性胰岛素治疗 (通过注射或胰岛素泵) 来维持生命。 由于 T1D 的自身免疫特性,研究人员已开始探索涉及 T 细胞和 B 细胞的疗法,以期延缓或治愈该疾病。尽管免疫疗法的初步结果令人鼓舞,但这些治疗手段未 能满足当前临床维持持久正常血糖水平和摆脱胰岛素依赖的需求。这凸显了对 T1D 免疫生物学进行更深入研究的必要性。 2026 年 1 月 21 日, 中南大学湘雅二医院 李霞 教授、 赵斌 教授等,在 Nature 子刊 Nature Metabolism 上发表了题为: IL-21 mediates crosstalk between T cells and NK cells during the remission of type 1 diabetes 的研究论文。 该研究确定了 CD226 + CD56 dim CD16 + NK 细胞 是 1 型糖尿病 (T1D) 缓解期的关键生物标志物。 ...
浙江大学×同济大学合作Science论文:内源逆转录病毒是开启人类胚胎发育的关键钥匙

撰文丨王聪 编辑丨王多鱼 排版丨水成文 在人类早期胚胎发育过程中, 合子基因组激活 (ZGA) 是一个关键事件,在此期间胚胎开始从自身基因 组转录。这一过程需要对染色质景观和转录网络进行全局性重排。ZGA 失败常常导致发育停滞,这是导致 不孕和妊娠失败的一个主要因素。尽管对哺乳动物 ZGA 模型的研究已经确定了对 ZGA 网络至关重要的关 键蛋白质编码基因,但人类 ZGA 失败和早期妊娠失败的原因仍知之甚少,这可能反映了物种间存在显著的 调控差异。 2026 年 1 月 22 日,浙江大学医学院 梁洪青 、 张丹 团队,联合同济大学 高绍荣 院士及浙江大学爱丁堡 大学联合学院 刘琬璐 团队 ( 向阳泉 、 钱羽力 、 李铮一 、 王佳旭 为论文共同第一作者) , 在国际顶 尖学术期刊 Science 上发表了题为: Endogenous retroviruses synthesize heterologous chimeric RNAs to reinforce human early embryo development 的研究论文。 该研究表明,一种古老的病毒残留物—— 内源逆转录病毒 MLT2A1 ,在 ...
Nature Aging:宋默识团队发现延缓心脏衰老的新靶点——LINE-1
生物世界· 2026-01-23 04:02
Core Viewpoint - Targeting age-related LINE-1 activation can alleviate cardiac aging, highlighting its potential as a therapeutic target for age-related cardiac dysfunction [4]. Group 1: Research Findings - The study indicates that the expression of LINE-1 in the heart increases with age [7]. - Researchers created heart-specific Mov10 gene knockout mice, which could not suppress LINE-1 expression, leading to LINE-1 de-repression, cardiac dysfunction, and early cardiac aging by three months of age [7]. - Activation of the cGAS-STING pathway was observed in these knockout mice, suggesting a link between LINE-1 and cardiac aging [7]. Group 2: Therapeutic Implications - The use of Lamivudine (3TC), a reverse transcriptase inhibitor, and H-151, which inhibits STING, both suppressed cGAS-STING activation and alleviated aging in new muscle cells from Mov10 knockout mice [7]. - Both inhibitors improved cardiac function in naturally aged mice and reduced cardiac inflammation and aging phenotypes [7]. - These findings suggest that LINE-1 and its downstream effectors could be potential targets for treating age-related cardiac dysfunction [7].

编辑丨王多鱼 排版丨水成文 埃博拉病毒病 ( Ebola virus disease, EVD) 由 埃博拉病毒 (EBOV) 引起,是一种致死率高达 90% 的动物源性感染,对全球卫生安全构成巨大挑战。埃博 拉病毒属于丝状病毒科,是一种负链 RNA 病毒,于 1976 年在刚果民主共和国首次被发现。在埃博拉病毒属的六个已知物种中,扎伊尔埃博拉病毒的毒性最强, 也是人类疫情中最常见的病原体。该病毒通过直接接触感染者的体液传播,果蝠被认为是其天然宿主,导致病毒反复从动物宿主溢出至人类。 自发现以来,已记录了 30 多次埃博拉病毒病疫情,通常局限于非洲的局部地区,但影响巨大。2014 - 2016 年的西非埃博拉疫情是史上规模最大的一次,感染 人数超过 28600 人,死亡人数达 11300 人,而 2018 - 2020 年刚果民主共和国爆发了史上第二大埃博拉疫情,导致了约 3400 例病例和 2200 人死亡,这凸 显了埃博拉病毒持续存在的公共卫生威胁。在大流行期间,病毒的关键变异往往会增强其致病性与传播力。那么,病毒变异是否也是此次埃博拉疫情 传播 的关键 因素? 2026 年 1 月 2 2 日,中山大学 ...
Cell重磅:鲁友明团队揭示癌症对抗阿尔茨海默病的机制,带来全新治疗思路
生物世界· 2026-01-23 00:21
Core Viewpoint - The research reveals a surprising link between peripheral cancers and a reduced risk of Alzheimer's disease, suggesting that certain cancer patients may possess a protective mechanism against Alzheimer's through the protein cystatin-c [2][6]. Group 1: Research Findings - The study published in Cell demonstrates that tumor cells secrete cystatin-c, which acts as a "molecular glue" to activate TREM2 receptors on microglial cells, facilitating the clearance of amyloid plaques associated with Alzheimer's disease [3][5]. - In experiments with Alzheimer's model mice implanted with peripheral cancer cells, a significant reduction in amyloid plaques and improved cognitive function were observed [6][12]. Group 2: Mechanism of Action - Cystatin-c binds to toxic amyloid oligomers in the brain, activates microglial cells via TREM2, and enhances the clearance of existing amyloid plaques [9][15]. - The protective effect of cystatin-c was confirmed through gene knockout experiments, where the absence of cystatin-c eliminated the protective benefits, which were restored upon reintroduction of normal cystatin-c [13][14]. Group 3: Therapeutic Implications - This research opens new avenues for Alzheimer's treatment by focusing on the removal of existing amyloid plaques rather than solely preventing their formation [17][21]. - Direct injection of recombinant cystatin-c into Alzheimer's model mice successfully reduced amyloid burden and improved learning and memory capabilities [18][20].
