• To identify future research directions in the field.

Main Methods:

• This is a review article, synthesizing existing research.
• Analysis of current literature on CLTA+ T cell phenotype, function, and disease association.
• Identification of knowledge gaps and future research priorities.

Main Results:

• CLTA+ T cells reflect regional immune functions of the skin.
• These cells are crucial players in the pathogenesis of diverse cutaneous diseases.
• The review consolidates current understanding and translational relevance.

Conclusions:

• CLTA+ T cells represent a significant therapeutic target in dermatology.
• Further research is needed to fully elucidate their role and harness their potential.
• Understanding CLTA+ T cells is vital for advancing skin immunology and disease treatment.
