4 syllables: in, ter, leu, kin. Stress on leu.
in-tur-LOO-kin
/ˌɪntɚˈlukɪn/
interleukin is pronounced in-tur-LOO-kin (/ˌɪntɚˈlukɪn/). It has four syllables (in-ter-leu-kin), with the stress on "leu". Interleukin refers to a group of cytokines produced by leukocytes that regulate immune responses, inflammation, and hematopoiesis. These signaling proteins facilitate communication between white blood cells, modulating cell growth, differentiation, and immune system coordination. They are central to immunology research and clinical contexts dealing with infection, cancer, and autoimmune diseases.

"The researchers studied interleukin-2 and its role in T-cell proliferation."
"Elevated interleukin-6 levels are often observed in inflammatory conditions."
"Dr. Smith discussed interleukin signaling pathways during the lecture."
Pronounce as in-ter-LEU-kin, with primary stress on the LEU syllable. IPA (US/UK): /ˌɪn.tər.luˈkaɪn/ in US, /ˌɪn.tə.ljuˈkaɪn/ in UK, roughly /ˌɪn.təˈljuː.kɪn/ in Australian usage. Break it into three clear parts: in- (unstressed), ter- (unstressed), LEU- (stressed) and -kin as a light, final syllable. Mouth positions: start with a neutral schwa or short i for in-, then a light “ter” with a relaxed tongue, then a long
Common errors: 1) stressing the wrong syllable (placing stress on IN-ter rather than LEU); 2) mispronouncing 'leu' as 'loo' or 'lee-you' instead of the correct 'LEU' (lyoo) vowel sequence; 3) merging -kin too strongly as /kɪn/ vs /kən/. Correction: emphasize IL-LEU-N with a clear /ləˈjuː/ or /luˈkaɪn/ depending on dialect; practice slow syllable segmentation: in-ter-leu-kin; keep the 'leu' vowel as a single nucleus and avoid dropping the final 'n'.
In US English, the word often surfaces as /ˌɪn.tər.luˈkaɪn/ with emphasis on LEU and a less rounded 'lu' glide. UK English tends to /ˌɪn.tə.ljuˈkaɪn/ with a light 'lj' sound between syllables, closer to 'lyoo'. Australian English commonly renders /ˌɪn.tə.ljuˈkaɪn/ with a slightly flatter vowel in the second syllable and less rhoticity influence, but the main stress remains on LEU. In all, the key differences are the treatment of the second syllable and the glide in 'leu'.
It combines a rarely used vowel cluster in 'leu' with a multisyllabic structure and a tertiary stress pattern. The 'leu' digraph can be pronounced as /ljuː/ or /luː/ depending on dialect, and the trailing -kin can blur into /kɪn/ or /kən/. The word’s length and the medical context can cause speakers to rush, misplacing stress or relaxing the consonants. Practice slow, isolated syllables and then blend them smoothly.
No. All letters in interleukin contribute to pronunciation, including the final -kin. Each syllable is pronounced: in-ter-leu-kin, with the vowels and consonants clearly articulated to avoid truncation. In rapid speech, the -er and -leu segments may blend slightly, but there is no silent letter in standard biomedical usage.

Interleukin is a compound word formed from inter- (between) and interleukin (a portmanteau of interleukin-1, etc.), from the cytokine family. The term interleukin emerged in the 1970s–1980s as scientists defined a class of soluble factors secreted by leukocytes that mediate interactions between white blood cells. The root inter- signals “between”; leukin derives from leukocyte/immune signaling nomenclature, with IL-1 as a foundational member. The naming convention evolved as researchers identified numerous IL molecules (IL-1, IL-2, IL-6, etc.), each with distinct receptors and functions. First recorded use appears in immunology literature in the late 1970s to early 1980s during the discovery and characterization of cytokines, and the term became standard by the 1990s as molecular immunology advanced. Today, interleukins are understood as a broad family of small secreted proteins about 16–40 kDa, functioning through receptor binding and downstream signaling cascades (JAK-STAT, MAPK), with roles in inflammation, hematopoiesis, and immune cell communication. The term is still frequently used in research reports, clinical trials, and therapeutic developments targeting IL pathways.
