Hypothesis

Combined NAMPT-Alectinib Targeting of SASP-Complement Cascade

Combined NAMPT-Alectinib Targeting of SASP-Complement Cascade starts from the claim that modulating NAMPT, SIRT1, C1QA/C1QB/C1QC, IL1B within the disease context of neuroinflammation can redirect a disease-relevant process.

🧪 Overview

Mechanistic Overview


Combined NAMPT-Alectinib Targeting of SASP-Complement Cascade starts from the claim that modulating NAMPT, SIRT1, C1QA/C1QB/C1QC, IL1B within the disease context of neuroinflammation can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Combined NAMPT-Alectinib Targeting of SASP-Complement Cascade starts from the claim that modulating NAMPT, SIRT1, C1QA/C1QB/C1QC, IL1B within the disease context of neuroinflammation can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Combined NAMPT-Alectinib Targeting of SASP-Complement Cascade starts from the claim that Senescence-Associated Secretory Phenotype Complements: NAMPT/NAD+ Axis Inhibition Synergizes with C1q Blockade to Interrupt Synaptic Degeneration Cascades. Alectinib blocks downstream effector arm (C1q-mediated synaptic phagocytosis) while NAMPT inhibitors interrupt upstream driver, creating synergistic complement suppression without global immune suppression. Framed more explicitly, the hypothesis centers NAMPT, SIRT1, C1QA/C1QB/C1QC, IL1B within the broader disease setting of neuroinflammation.
