Abstract
Langerhans' cells migrating from contact-sensitized skin were found to up-regulate expression of macrophage-derived chemokine (MDC) during maturation into lymph node dendritic cells (DCs). Naı̈ve T cells did not migrate toward MDC, but antigen-specific T cells rapidly acquired MDC responsiveness in vivo after a subcutaneous injection of antigen. In chemotaxis assays, maturing DCs attracted activated T cells more strongly than naı̈ve T cells. These studies identified chemokine up-regulation as part of the Langerhans' cell maturation program to immunogenic T cell–zone DC. Preferential recruitment of activated T cells may be a mechanism used by maturing DCs to promote encounters with antigen-specific T cells.

This sequence is identical to the recently described mouse ABCD1 sequence (8). An 800–base pair Eco RI fragment containing the coding region was used as a probe for Northern blot analysis and digoxigenin-based in situ hybridization was performed as described (4). RT-PCR was performed with primers specific for MDC (5′-GTGGCTCTCGTCCTTCTTGC-3′ and 5′-GGACAGTTTATGGAGTAGCTT-3′) ELC (4) or actin. Mature mouse MDC (amino acids 25 to 92) was expressed in Escherichia coli as described for ELC (4).

Mice shown in Fig. 2A were painted on the shaved thorax and abdomen with 0.4 ml of 2% FITC (Sigma) dissolved in a 1:1 (v/v) acetone/dibutyl phthalate (Sigma) mixture and RNA was prepared from pooled brachial inguinal and axillary nodes. For other experiments a region of mouse skin on the arm or flank was shaved 25 μl of 1% FITC in acetone/dibutyl phthalate was applied onto each region and the draining nodes (brachial and inguinal) were analyzed 1 day later.

- Mouse ear epidermal cells were isolated and cultured as described (22). In some cases cells were stained with anti–MHC class II (I-A b ) sorted to >93% MHC class II high LCs and used for RNA preparation. To purify DCs that were newly migrating into lymph nodes we painted the skin of mice with FITC (18) and 1 day later we collected draining lymph nodes and gently mashed them through a 70-μm mesh cell strainer. DCs in cell suspensions prepared without enzymatic digestion were enriched for FITC + cells which is consistent with findings that monocyte-derived DCs are more easily isolated from lymphoid tissues than other DC types (1). To prepare RNA we sorted DCs to >95% B220 – FITC + I-A b -hi cells. For chemotaxis assays DCs from ∼18 FITC-painted mice per experiment were enriched with metrizamide and either immediately put into culture or first sorted to >90% B220 – CD11c + . Cells were cultured in serum-free medium (Mediatech Herndon VA) at 2 × 10 6 to 5 × 10 6 cells/ml for 1 day. The stromal material that did not enter suspension after mechanical mashing contained SLC-expressing cells and ELC-expressing resident DCs (4 14). Stromal preparations from 30 to 40 brachial and axillary nodes per experiment were cultured overnight in 2 ml of serum-free medium to provide supernatant for chemotaxis assays.

Draining (pool of brachial axillary and inguinal) and nondraining (mesenteric) lymph node cells were isolated 1 to 5 days later and used in MDC chemotaxis assays. The frequency of OVA-specific T cells that migrated was measured with the clonotypic antibody to TCR KJ1-26 (28). Overnight incubation of day 2 draining lymph node cells (at 10 7 cells/ml) in medium containing interleukin-2 (IL-2) (4 ng/ml) increased the sensitivity of activated KJ1-26 + cells to MDC (14). Therefore IL-2–cultured cells were used in experiments to detect chemokine production by purified lymph node DCs and stromal cells.
