Crosstalk Between Upr And Mitochondria: The Triad Of Er-Mitochondria Contacts, Ca²⁺, And Ros, Ester Zito, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Endoplasmic reticulum (ER) stress is triggered by several cellular perturbations causing protein misfolding, and activates the unfolded protein response (UPR), an initially adaptive signaling network that aims to restore ER and cellular homeostasis. Growing evidence indicates that UPR signaling extends beyond ER proteostasis, influencing mitochondrial function and bioenergetics through ER-mitochondria contact sites (ERMCs). The CHOP-ERO1A-IP3R axis has a primary role in recruiting mitochondria to adaptive UPR. However, its sustained activation renders UPR signaling maladaptive, leading to mitochondrial dysfunction through both outer mitochondrial membrane permeabilization (OMMP) and mitochondrial permeability transition pore (mPTP) opening, ultimately contributing to irreversible cell injury and disease …

How Do Governments Combat Jihad Online?, Noah Cook

Honors College Theses

Since the September 11th, 2001 attacks, jihadist groups like ISIS, al-Qaeda, and al-Shabaab have used the internet as a tool for recruitment, radicalization, and propaganda dissemination. Since then, governments, non-governmental organizations, and private companies have developed strategies to combat jihadism on the internet. This paper examines how these actors have worked to mitigate the digital jihadist footprint and its effects by analyzing three main approaches to countering violent Islamist extremism on the internet: counter narrative initiatives, awareness-raising programs, and content removals. This paper finds that each of these methods has its own strengths and weaknesses. Counter narrative campaigns show the …
