You will be given a definition of a task first, then some input of the task.
Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Although elevated serum IgE levels have been reported in psoriasis, the role of IgE in psoriasis still needs to be clarified.', 'To analyse serum total IgE levels in addition to the presence and distribution of IgE and FcRI in psoriatic lesions, and to investigate alteration of IgE and FcRI after successful systemic treatment.', 'Total serum IgE levels were determined using enzyme-linked immunosorbent assay. The expression and localization of IgE and FcRI was investigated using immunohistochemistry and double immunofluorescence.', 'Elevated total serum IgE levels were found in 39% of patients with psoriasis. The levels of total serum IgE were significantly higher in male patients compared with female patients. Furthermore, total serum IgE levels decreased after successful systemic treatment. A positive correlation between IgE+ and FcRI+ cells and a significant increase of these cells was found in psoriatic lesions when compared with normal skin. Interestingly, IgE+ and FcRI+ cells decreased significantly after successful therapy with ustekinumab. IgE and FcRI were coexpressed on mast cells, epidermal Langerhans cells, dermal dendritic cells, macrophages and a small number of neutrophils.
Output:
Are igE and FcRI highly expressed on innate cells in psoriasis?
