LIFR - Leukemia Inhibitory Factor Receptor

Introduction

Lifr Leukemia Inhibitory Factor Receptor is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Overview

LIFR (Leukemia Inhibitory Factor Receptor) is a cytokine receptor that transduces signals from leukemia inhibitory factor (LIF) and related cytokines. It plays crucial roles in neural development, stem cell maintenance, and neuroprotection. The LIFR is essential for mediating the neuroprotective effects of the LIF cytokine family in the central nervous system.

Gene Information

• Official Symbol: LIFR
• Official Full Name: Leukemia Inhibitory Factor Receptor Alpha
• Chromosomal Location: 5p13.1
• Gene ID: 3977
• Protein: LIF Receptor Alpha
• UniProt ID: P15090

Function

LIFR forms a signaling complex with gp130 (IL6ST):

• LIF binding: High-affinity interaction with LIFR
• CNTF binding: Via CNTFRα with LIFR/gp130
• Oncostatin M (OSM): LIFR can also signal for OSM
• Cardiotrophin-1 (CT-1): Cardiotrophin family signaling

Signaling Pathways

• JAK/STAT3 pathway: Primary signaling cascade
• PI3K/Akt pathway: Pro-survival signals
• MAPK/ERK pathway: Differentiation signals

• Therapeutic potential being explored

Stroke and Brain Injury

LIFR signaling is neuroprotective:

• LIF is neuroprotective in ischemic stroke[@slaets2010]
• Promotes neural repair
• Reduces infarct size
• Enhances functional recovery

Alzheimer's Disease

LIF signaling may have beneficial effects:

• Modulates neuroinflammation
• Supports neuronal survival
• May affect amyloid pathology

Expression Pattern

• Brain: [Neurons](/entities/neurons), [astrocytes](/entities/astrocytes), neural stem cells
• Spinal cord: Motor neurons
• Peripheral: Various tissues including heart, lung, liver
• Developmental: High expression during neural development
• Adult: Moderate expression maintained

Therapeutic Implications

LIFR Agonists

Therapeutic strategies targeting LIFR:
