[Correction of immunity disorder developing after craniocerebral trauma]

Area of Science:

• Immunology
• Trauma Research
• Biochemistry

Background:

• Cranial trauma can induce significant physiological stress, negatively impacting immune function.
• The thymus, crucial for T-cell development, is vulnerable to stress-induced damage.
• Understanding the body's response to injury is key to developing therapeutic interventions.

Purpose of the Study:

• To investigate the immunomodulatory effects of a humoral factor derived from injured animal serum.
• To determine if this factor can mitigate the negative immune consequences of trauma.
• To assess the timing and nature of the observed immune responses.

Main Methods:

• Administration of a humoral factor isolated from the blood serum of injured animals.
• Evaluation of thymus integrity post-trauma.
• Assessment of humoral immune response using sheep erythrocytes as a test antigen.
• Measurement of delayed-type hypersensitivity (HDT) reactions.

Main Results:

• The humoral factor administration prevented stress-induced thymus atrophy.
• Improved humoral immune response to sheep erythrocytes was observed.
• Restoration of delayed-type hypersensitivity (HDT) reactions was noted.
• Immune-stimulating effects were evident both immediately after trauma and 5-7 days later.

Conclusions:

• A specific humoral factor in serum from injured animals possesses significant immunoprotective and immunomodulatory properties.
• This factor can counteract trauma-induced immune suppression, offering potential therapeutic benefits.
• The observed effects highlight the complex interplay between injury, stress, and the immune system.
