In thee context of autoimmunology, thee key cellular targes are T cells, B cells, macrophages, and dendritic cells - thee main drivers of self-directed difficultion. Light-activated therapes can induce apoptosis (programmed cell death) in overactive lymphocytes, reduce pro- difficulmatory cytokinene production (e.g., TNF- α, IL- 17, IL- 6), and upregulate anti- divimatory mediators such aIL- 10.

Major Types of Light- Activated Therapies in Autoimmunology

Three primary modalities have emerged as frontrunners in autoimmunole research: photodynamic therapy (PDT), low- level light therapy (LLLT), and photoimmunotherapy. Each operates thoplugh distrant mechanisms andd is phased two different clinical contricos.

In autoimmunole applications, PDT has been investigated for reumatoidad artritis, duscasis, and even multiple sclerosis.

Low- Level Light Therapy (LLLT)

Fotoimmunoterapia

Photoimmunoterapia (PIT) represents a convergence of photodynamic techniques with provided immunotherapy. In this approvach, a photosensitiser is concorgated to a monoclonal antibody or antibody fragment that binds specifically to antigens expressed on overactive immate cells - for example, CD25 on regulatory T cells or CD20 on B cells. When light is appled, thee photosensitiser is activated only on cells that have bound the antiboy, leading tashlocalisased cell death modulation.
