まとめ
オートログ性メゼンキマ幹細胞 (MSC) は,腎臓移植患者における急性拒絶および機会性感染症を減少させた. このアプローチは,標準的な抗体誘導療法と比較して腎機能を改善し,移植受容者にとって有望な代替案を提供しました.
科学分野:
- ネフロロジーはネフロロジーを用います.
- 免疫学 免疫学とは
- 再生医学は,再生医療である.
背景:
- 腎臓移植は,急性拒絶症,好機性感染症,カルシヌーリンの阻害剤 (CNI) 毒性により困難です.
- メセンキマル幹細胞 (MSC) は,移植対宿主疾患の治療に潜在力を示しています.
研究 の 目的:
- 腎臓移植受信者における抗体誘導療法の代替として,オトログのMSCを評価する.
- 生きた親戚のドナーからのABO互換,クロスマッチ陰性移植におけるMSCの有効性と安全性を評価する.
主な方法:
- 159人の腎臓移植患者が参加した前向きな,オープンラベル,ランダム化研究です.
- 患者は再注射時に,移植後2週間で骨髄由来のMSCをオトログで受けた.
- 比較グループには標準用量CNI,低用量CNI,標準用量CNIとIL-2受容体抗体が含まれていました.
主要な成果:
- オトログのMSCは,生検で確認された急性拒絶の1年間の発生率を大幅に低下させました (対照群では7.5-7.7%対21.6%).
- MSC治療により,腎機能の回復がより迅速 (eGFRの増加) になり,好機性感染症のリスクが低下しました (HR 0.42).
- MSC群では,対照群 (P=.02) と異なり,グルココルチコイド耐性拒絶症は発生しなかった.
結論:
- オートロゴスMSCは,腎臓移植における抗体誘導療法に有効な代替手段を提供します.
- MSCの使用は,より低い急性拒絶率,機会性感染症の減少,および腎機能の改善をもたらしました.
- このアプローチは,患者のアウトカムと腎臓移植受容者の安全性を向上させます.

Self-Evaluation: Self-Enhancement and Self-Verification
4.7K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

General State of Stress
916
The general state of stress within a material can be accurately depicted using a stress tensor. This tensor encapsulates the internal forces distributed within a material subjected to external forces or deformations.
Specifically, consider a tetrahedral element where one face, labeled XYZ, is perpendicular to the line OA, and the remaining faces align with the coordinate axes with point O as the origin. At any point, such as point O, the stress tensor can be used to determine the stress...

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Psychological Responses to Stress
976
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
