Title Slide: Concept of Immunity – Tissue Resolution and Repair
Slide 2: Introduction
– Immunity is a multifaceted biological defense mechanism that protects organisms against pathogens
– The immune system is composed of various cells, tissues, and organs that work together to identify and eliminate foreign substances
– This presentation will focus on the processes of tissue resolution and repair, as well as the dysfunctional wound healing process within the context of immunity
Slide 3: Tissue Resolution and Repair
– Tissue resolution refers to the restoration of normal tissue structure and function following injury or inflammation
– Damaged tissues undergo a series of coordinated events involving multiple cell types and mediators
– Macrophages, neutrophils, and other immune cells play critical roles in removing debris and promoting tissue repair
Slide 4: Wound Healing Process
– Wound healing is a complex biological process that aims to restore the integrity of damaged tissues
– The process can be divided into three overlapping phases: inflammation, reconstructive, and maturation
– Each phase involves specific immune responses and cellular activities
Slide 5: Inflammatory Response during Wound Healing
– During the inflammatory phase, the immune system initiates a cascade of events to control bleeding and prevent infection
– Hemorrhage occurs as blood vessels in the wound are damaged, leading to blood clot formation
– Fibrous adhesion involves the formation of connective tissue fibers to support wound closure
– Infection is a potential complication, as pathogens can enter the wound site and trigger an immune response
Slide 6: Dysfunctional Wound Healing during Inflammation
– Dysfunctional wound healing can arise due to various factors, including impaired immune responses or excessive inflammation
– Hemorrhage can result from a compromised clotting mechanism or persistent bleeding
– Fibrous adhesion may become excessive, leading to scar tissue formation and reduced tissue flexibility
– Infection can occur if the immune response fails to eliminate invading pathogens efficiently
Slide 7: Dysfunctional Wound Healing during the Reconstructive Phase
– The reconstructive phase involves the formation of new tissue and the restoration of functional integrity
– Keloid and hypertrophic scars arise from abnormal collagen deposition, leading to raised and thickened scars
– Impaired epithelialization refers to delayed or incomplete re-epithelial layer formation, delaying wound closure
– Dehiscence is the partial or complete separation of wound edges, impairing the healing process
– Contracture occurs when excessive wound contraction leads to tissue distortion and limited range of motion
Slide 8: Conclusion
– Tissue resolution and repair are crucial for wound healing and restoration of tissue integrity
– Dysfunctional wound healing can occur during both the inflammatory and reconstructive phases
– Understanding the immune response in the context of wound healing is vital for developing effective therapeutic interventions
