Heather D. Edginton, Jeanine Peters-Kennedy and Danny W. Scott Resident lymphocytes in the dermis of the normal dorsolateral thoracic skin of alpacas Veterinary Dermatology 25
Background – Small numbers of resident T lymphocytes are present in the dermis of normal skin of humans, cattle and sheep. Hypothesis/Objectives – We wanted to determine the prevalence, numbers and immunophenotype of lymphocytes in the dermis of healthy skin from alpacas. Conclusions and clinical importance – Resident CD3+ and CD79a+ lymphocytes are present around superficial and deep dermal blood vessels in normal skin from alpacas; hence, the presence of lymphocytes in these locations without obvious features of inflammation must be interpreted cautiously when evaluating skin biopsy specimens from alpacas with skin disease.
