SCF ENCYCLOPEDIA ENTRY

TICK-BORNE ENCEPHALITIS (TBE)

I. SCOPE & POSITIONING

Pathogen / Etiology: Tick-borne encephalitis virus

Classification: Viral (Flaviviridae family; positive-sense single-stranded RNA virus)

Transmission:

• Tick bite (primarily Ixodes species)
• Rare: consumption of unpasteurized dairy products

Primary Tropism:

Central nervous system (CNS), especially brain and spinal cord

SCF Classification:

Vector-Borne Neurotropic Biphasic Inflammatory Encephalitic Degenerative Disorder (VNBIEDD Class)

II. GLOBAL & CLINICAL SIGNIFICANCE

• Endemic in parts of:
• Europe
• Russia
• East Asia
• Seasonal (spring–summer; tick activity)

Clinical Hallmarks:

• Biphasic illness pattern
• Fever and flu-like symptoms (initial phase)
• Neurological symptoms (second phase)

Severe Complications:

• Encephalitis
• Meningitis
• Myelitis
• Long-term neurological deficits

Aligned SCF Clinical Domains:

• C3: Neuroimmune Systems
• C2: Infectious & Inflammatory Medicine
• C12: Vector-Borne Viral Diseases

III. ETIOPATHOGENIC CORE

Primary Mechanisms:

• Viral entry via tick saliva
• Initial replication in skin and lymph nodes
• Viremia
• CNS invasion (crossing blood–brain barrier)

Key Drivers:

• Neurotropism
• Immune-mediated inflammation
• Blood–brain barrier disruption

IV. SCF FAULT ARCHITECTURE

Key Insight:

TBE is a neuroinvasive viral disorder, where immune response within the CNS contributes significantly to pathology.

V. MULTI-OMICS PATHOGENESIS MAP (Neurotropic Viral Model)

A. Genomics

• RNA genome with strain variability
• Subtypes:
• European
• Siberian
• Far Eastern (more severe)

B. Transcriptomics

• Activation of inflammatory pathways
• Upregulation of cytokine signaling

C. Proteomics

• Envelope (E) protein:
• Mediates cell entry
• Nonstructural proteins:
• Facilitate replication and immune evasion

D. Epigenomics

• Persistent inflammatory signaling in CNS
• Potential long-term neuroimmune changes

E. Metabolomics

• Altered neuronal metabolism
• Energy deficits in CNS

F. Interactomics

• Virus–neuron interaction
• Immune cell infiltration into CNS

G. Neurovascular Interface

• Blood–brain barrier permeability
• Neuroinflammation
• Neuronal injury

VI. PATHOGENESIS FLOW (SCF LOGIC)

Tick bite → Local replication → Viremia → Temporary remission → CNS invasion → Neuroinflammation → Neurological damage

VII. CLINICAL SPECTRUM

Phase 1 (Viremic Phase)

Features:

• Fever
• Fatigue
• Headache
• Myalgia

SCF Tier:

Tier I–II

Phase 2 (Neurological Phase)

Features:

• Meningitis
• Encephalitis
• Confusion
• Paralysis

SCF Tier:

Tier III–IV

Recovery / Chronic Phase

Features:

• Cognitive deficits
• Motor dysfunction
• Fatigue

VIII. SCF DISEASE-ORIGIN MODEL

A. Core Mechanisms:

• Vector-mediated transmission
• CNS invasion
• Immune-mediated neurodamage

B. SCF Classification:

• Primary: Neurotropic Viral Infection
• Secondary: Neuroinflammatory Degenerative Disorder

IX. SCF TRINITY FRAMEWORK MAPPING

Interpretation:

TBE represents a neuroinflammatory invasion model, where viral entry into CNS triggers damaging immune responses.

X. SCF PCR THERAPEUTIC STRATEGY

1. PREVENTATIVE (P)

• Vaccination (available in endemic regions)
• Tick avoidance:
• Protective clothing
• Repellents
• Food safety (avoid unpasteurized dairy)

2. CURATIVE (C)

• No specific antiviral therapy

Supportive Care:

• Hospitalization (moderate–severe cases)
• CNS monitoring
• Management of complications

3. RESTORATIVE (R)

• Neurological rehabilitation
• Cognitive therapy
• Long-term monitoring

XI. CURRENT STANDARD OF CARE

• Preventative vaccination
• Supportive management
• Rehabilitation for neurological sequelae

XII. SCF THERAPEUTIC ENGINEERING OPPORTUNITIES

High-Value Targets:

• Viral entry into neurons
• Blood–brain barrier crossing mechanisms
• Neuroinflammatory pathways

SCF Design Strategy:

• Neuroprotective antivirals
• BBB-stabilizing agents
• Immune-modulating therapies

XIII. RHENOVA INTEGRATION (REDOX–HYPOXIA LOGIC)

Core Disruption:

• CNS inflammation → oxidative stress
• Neuronal hypoxia
• Mitochondrial dysfunction

SCF–RHENOVA Role:

• Monitor brain oxygenation
• Guide neuroprotective interventions
• Predict long-term outcomes

XIV. TRANSLATIONAL BLUEPRINT (FDA-ALIGNED)

Preclinical:

• Neurotropic viral models
• Vaccine development

Clinical:

• Prevention via vaccination
• Early detection of CNS involvement
• Rehabilitation outcomes

Biomarkers:

• CSF analysis (pleocytosis)
• TBE virus antibodies (IgM, IgG)
• Neuroimaging (MRI)

XV. SCF DBI INTERPRETATION

Insight:

TBE represents a DBI neuroinflammatory invasion model, where CNS immune responses drive long-term damage.

XVI. SCF LAYMAN’S TRANSLATION SUMMARY

Tick-borne encephalitis is a viral infection spread by tick bites that can affect the brain.

It:

• Starts with flu-like symptoms
• Can progress to serious brain inflammation
• May cause long-term neurological problems

SCF treatment focuses on:

• Preventing infection with vaccines and avoiding ticks
• Supporting the body during illness
• Helping recovery after brain involvement
